Suppose a machine has two caches, an Ll cache and an L2 cache. Assume the following characteristics of cache performance: The processor is able to execute an instruction every cycle, assuming there is no delay fetching the instruction or fetching the data used by the instruction. An L1 cache hit provides the requested instruction or data immediately to the processor (i.e. there is no delay). An L2 cache hit incurs a penalty (delay) of 10 cycles. . . Fetching the requested instruction or data from memory – which happens when there is an L2 miss – incurs a penalty of 100 cycles. That is, the total delay is 100 cycles on an L2 miss, don't add the 10-cycle delay above. The L1 miss rate for both instructions and data is 3%. That is, 97% of instruction and data fetches result in an L1 cache it. The L2 miss rate for instructions is 1% and for data is 2%. That is, of those instruction fetches that result in an Ll cache miss, 99% of them will result in an L2 cache hit. Similarly, of those data fetches that result in an Ll cache miss, 98% of them will result in an L2 cache hit. 30% of instructions require data to be fetched (the other 70% don't). Given a program that executes I instructions, how many cycles would the program take to execute, under the above assumptions? Be sure to show your work. b. Suppose you are manufacturer of the above machine and, in the next release, you have the option of increasing the size of the Ll cache so that the Ll miss rate is reduced by 50% for both data and instructions or increasing the size of the L2 cache so that the L2 miss rate is reduced by 50% for both data and instructions. If your only goal was to make the above program faster, which option would you choose? Show your work. a.
Total number of cycles required to execute the program under option 2= 0.10639I + 1.2917I = 1.39809I. Therefore, we would choose option 2 which is to increase the size of the L2 cache so that the L2 miss rate is reduced
A given program that executes I instructions, under the given assumptions, the number of cycles it would take to execute it are; Number of instructions that require data to be fetched = 0.3I;Number of instructions that do not require data to be fetched = 0.7I;L1 miss rate for both data and instructions = 3%;L2 miss rate for instructions is 1% and for data is 2%;Number of instruction fetches that result in an L1 cache miss = 0.03 x I = 0.03I;Number of instruction fetches that result in an L1 cache hit = 0.97 x I = 0.97I;Number of data fetches that result in an L1 cache miss = 0.03 x 0.3I = 0.009I
Number of data fetches that result in an L1 cache hit = 0.97 x 0.3I = 0.291I;Number of instruction fetches that result in an L1 miss and an L2 cache hit = 0.99 x 0.03I = 0.0297I;Number of data fetches that result in an L1 miss and an L2 cache hit = 0.98 x 0.009I = 0.00882I;Therefore, the total number of cycles required to execute the program is: Number of cycles required for instructions that require data to be fetched = (0.03I x 10) + (0.009I x 110) + (0.0297I x 10) = 0.468I.

Question 23 An associative mapping the memory of (ed witamin memory than we tok word slot me number of topor man memory word
17. The CPU requests to load the following words in order A BAC, the words are stored in the cache after these requests is B and A. 23 An associative mapping the memory of the number of top-order memory words that can map to a word slot in the cache memory is called the associativity of the cache.
The cache memory is using FIFO strategy to replace words and can store up to 2 words at the same time, the CPU requests to load the following words in order A BAC. In FIFO strategy, we replace the oldest entry in the cache memory. Hence, the word A will be stored in the first memory word slot and then the word B will replace the word A. The updated cache memory will have the words B and an empty slot. Then the word A will be stored in the empty slot and the updated cache memory will have the words B and A. So, the words stored in the cache memory after these requests are B and
Associative mapping allows multiple cache words to map to a single memory word. The advantage of associative mapping is that we do not need to know the memory address for accessing the cache memory, making it faster. But, it requires additional hardware to implement the mapping.In this question, we are given the number of top-order memory words. However, we need the associativity of the cache to determine the number of memory words that can map to a single word slot in the cache memory. So therefore, the number of top-order memory words that can map to a word slot in the cache memory is called the associativity of the cache.

The outermost loop is executed n times, the second loop is executed n times for each execution of the outermost loop. Hence, the second loop is executed n*n = n² times.
Similarly, the innermost loop is executed n times for each execution of the second loop, giving a total of n*n*n = n³ iterations of the innermost loop. Each iteration of the innermost loop involves one addition and one modulus operation. Therefore, the total number of operations can be calculated as n x n² x (2 x 1) = 2n³.

i) To find the power spectral density of x(t), we need to follow the below steps:
Given x(t) = Ao g (t) = Ao (t + 4) (1 + δ (t)) + Ao (t - 4) (1 + δ (t))
Given that, A0 = 1 & G (f) = sin2πfT/T(πfT)/(πfT) = (sinπfT)/(πfT) (In rectangular form)
From this, we can obtain the power spectral density of x(t)P(f) = [A0/2G(f)]2
Thus, P(f) = [1/(2*(sinπfT)/(πfT))]2
On simplification, P(f) = [(πfT)/2]2Thus, the power spectral density of x(t) is P(f) = (πfT)2/4.
ii) If we use precoding of the form bn-an-an-1, the power is given by:
P = [(Ao)2 + (Bo)2 + (Co)2 + (Do)2]P = [A02 + (A0 - A1)2 + (-A1)2 + (-A1)2]P = 3 (A0)2 + 2 (A1)2

A causal linear invariant system is represented by the following difference equation M[n]-[n-1]+[-2] = x[n] Find the transfer function of the system; If the system input is x[n] = (u[r]. find the response of the system y[r].
The response of the system y[n] is given asy[n] = δ[n] - (1 / 2^n) u[n] - δ[n - 1] + (1 / 2^(n - 1)) u[n - 1]
From the question above, difference equation isM[n] - M[n - 1] + M[n - 2] = x[n]
The transfer function H(z) of a system is defined as the ratio of the Z-transforms of the output Y(z) to the input X(z) when all initial conditions are zero.
Thus, the transfer function H(z) of a system is given as
H(z) = Y(z) / X(z)
The Z-transform of the input signal x[n] isX(z) = 1 / (1 - z^(-1))
The Z-transform of the output signal y[n] isY(z) = H(z) X(z)
Thus, the Z-transform of the difference equation is given asY(z) = H(z) X(z) = H(z) / (1 - z^(-1))
Therefore, the transfer function H(z) of the system can be obtained as follows:
M(z) - z^(-1) M(z) + z^(-2) M(z) = X(z)H(z) = Y(z) / X(z) = M(z) / [1 - z^(-1) + z^(-2)]
Substituting x[n] = (u[n]) in difference equationM[n] - M[n - 1] + M[n - 2] = x[n]M[n] - M[n - 1] + M[n - 2] = u[n]
The input signal x[n] = (u[n]) can also be written asx[n] = u[n] - u[n - 1]
Using Z-transform of x[n],X(z) = 1 / (1 - z^(-1)) - z^(-1) / (1 - z^(-1))
Taking Z-transform of the difference equation,M(z) - z^(-1) M(z) + z^(-2) M(z) = X(z)M(z) (1 - z^(-1) + z^(-2)) = X(z) (1)M(z) = X(z) / (1 - z^(-1) + z^(-2))M(z) = [1 / (1 - z^(-1) + z^(-2))] / [1 / (1 - z^(-1))]M(z) = (1 - z^(-1)) / (1 - 2z^(-1) + z^(-2))
Thus, the transfer function of the system isH(z) = (1 - z^(-1)) / (1 - 2z^(-1) + z^(-2))
Substituting the value of x[n], x[n] = (u[n]), in the difference equation,M[n] - M[n - 1] + M[n - 2] = u[n]
Therefore, the difference equation of the system can be written asM[n] - M[n - 1] + M[n - 2] = u[n]M[n] = M[n - 1] - M[n - 2] + u[n]
The output signal y[n] can be obtained by convolving the input signal x[n] with impulse response h[n]y[n] = x[n] * h[n]
Where, h[n] is the inverse Z-transform of the transfer function H(z)
.h[n] = (1 / (1 - z^(-1))) - (1 / (1 - 2z^(-1) + z^(-2)))
Taking inverse Z-transform of H(z),h[n] = δ[n] - (1 / 2^n) u[n]
Thus, the output signal y[n] can be written asy[n] = x[n] * h[n]y[n] = (u[n] - u[n - 1]) * h[n]y[n] = δ[n] - (1 / 2^n) u[n] - δ[n - 1] + (1 / 2^(n - 1)) u[n - 1]

What is the effect of multiplying by (-1)x+y the spatial-domain image before applying the 2-D DFT? Explain briefly.
Multiplying by (-1)^(x+y) the spatial-domain image before applying the 2-D DFT results in the image being shifted by half a pixel both horizontally and vertically. This is known as the centering operation, and it has several benefits.
Firstly, centering the image prior to applying the DFT ensures that the DC component of the frequency spectrum (i.e., the component with zero frequency) is located at the center of the transformed image, rather than at one of the corners.
This helps to reduce the occurrence of aliasing artifacts in the transformed image .
In summary, multiplying by (-1)^(x+y) before applying the 2-D DFT centers the image, ensuring that the DC component of the frequency spectrum is located at the center of the transformed image and reducing the effects of aliasing.

A continuous rectification column is to be designed to seperate a mixture of 33.45 % (w/w) methanol and water into an overhead product containing 95.5% (w/w) methanol using a reflux ratio 1.3 times the minimum value. A bottom product contains 3.25 % (w/w) water. The distilate product rate is 1745 kg/h. The feed is a mixture of two-thirds vapor and one third liquid. Methanol and water can be considered as ideal system with a relative volatility of about 3.91. Design a rectification column using parameters above.
A rectification column with approximately 6 theoretical stages is required to achieve the desired separation of methanol and water using the given specifications and design parameters.
To design the rectification column, we need to determine the number of theoretical stages required and the reflux ratio based on the given specifications. Here's the design process:
1. Determine the minimum reflux ratio (Rmin):
The minimum reflux ratio can be calculated using the Fenske equation:
Rmin = (L/D)min = (V/F)min = α / (α - 1)
where α is the relative volatility of the key component, which is 3.91 in this case.
Rmin = 3.91 / (3.91 - 1) = 1.955
2. Calculate the actual reflux ratio (R):
R = Rmin * 1.3 = 1.955 * 1.3 = 2.5395
3. Determine the key component compositions:
Overhead Product (Distillate): 95.5% methanol, 4.5% water
Bottom Product: 3.25% methanol, 96.75% water
4. Calculate the key component flow rates:
Distillate flow rate (D): 1745 kg/h * 0.955 = 1666.975 kg/h (methanol)
Bottom flow rate (B): 1745 kg/h * 0.0325 = 56.70625 kg/h (water)
5. Determine the feed flow rate (F):
The feed consists of two-thirds vapor and one-third liquid, so:
F = D / (α - 1) + B / (1 - α) = 1666.975 / (3.91 - 1) + 56.70625 / (1 - 3.91)
F = 958.3125 kg/h (total feed)
6. Calculate the reflux flow rate (L):
L = R * D = 2.5395 * 1666.975 = 4232.784 kg/h
7. Determine the key component compositions at various stages:
At the top stage (overhead product):
Xmethanol = 0.955 (given)
Xwater = 1 - Xmethanol = 1 - 0.955 = 0.045
At the bottom stage (bottom product):
Xmethanol = 0.0325 (given)
Xwater = 1 - Xmethanol = 1 - 0.0325 = 0.9675
8. Determine the number of theoretical stages (N):
N = log((Xbottom - Xtop) / (Xtop - Xfeed)) / log(R)
N = log((0.9675 - 0.045) / (0.045 - 0.0333)) / log(2.5395)
N ≈ 5.83
Since the number of theoretical stages should be an integer value, we round up to the next whole number:
N = 6
Therefore, a rectification column with approximately 6 theoretical stages is required to achieve the desired separation of methanol and water using the given specifications and design parameters.

3. (10 pts) Consider the standard square 25-QAM signal constellation. We can form another constellation with 25 points by taking the union of the standard square 16-QAM and 9-QAM constellations. (a) (4 pts) Sketch the upper right quadrant for each constellation. I.e., plot the points ï in the constellation with Re[x] ≥ 0 and Im[x] ≥ 0. (b) (6 pts) Which constellation has better power efficiency? (You can answer this by computing the power efficiencies in each case, but there is an easier way. If you do decide to compute the efficiencies, it is possible to avoid large sums.)
The 25-QAM constellation has a minimum distance squared of 20, which is greater than the minimum distance squared of the 16-QAM and 9-QAM constellations. Thus, the 16-QAM and 9-QAM constellations have better power efficiency than the 25-QAM constellation.
Part A) Here are the sketches of upper right quadrant for each constellation, with the points in the constellation with Re[x] ≥ 0 and Im[x] ≥ 0. 16-QAM25-QAM9-QAM25-Point constellationPart B) Power efficiency refers to how efficiently a particular modulation scheme uses power. The power efficiency in a QAM constellation is defined as the minimum distance squared between any two points in the constellation. The minimum distance squared is inversely proportional to the power efficiency. The minimum distance squared for the standard 25-QAM constellation is `2d^2`, where `d` is the distance between two adjacent points in the constellation. The distance between the adjacent points in a 25-QAM constellation is `2*sqrt(10)`. Thus, `d
= square root(10)`. So, the minimum distance squared is `2(10)
= 20`.The minimum distance squared for the 16-QAM constellation is `2(2d^2)
= 8d^2`. Thus, the distance between adjacent points is `2d
= 2*square root(2)`. Thus, the minimum distance squared is `8(2)
= 16`.The minimum distance squared for the 9-QAM constellation is `2(2d^2)
= 8d^2`. Thus, the distance between adjacent points is `2d
= 2*sqrt(2)`. Thus, the minimum distance squared is `8(2)
= 16`.Therefore, the 16-QAM constellation and the 9-QAM constellation have the same minimum distance squared and thus have the same power efficiency. The 25-QAM constellation has a minimum distance squared of 20, which is greater than the minimum distance squared of the 16-QAM and 9-QAM constellations. Thus, the 16-QAM and 9-QAM constellations have better power efficiency than the 25-QAM constellation.

elbow, assuming a centerline distance of 3 ′
⋅87/8 ′′
?
The plant production is estimated to be 24 tons per hour. The information does not include the diameter of the pipe, which is necessary to calculate the square footage.
To estimate the plant production in tons per hour, we need to calculate the effective production rate considering the mixing cycle and plant efficiency.
Given:
Total asphalt mix: 24 tons
Mixing cycle: 1.5 minutes
Plant efficiency: 85%
First, we calculate the effective production rate per cycle:
Effective Production Rate = Total Asphalt Mix / Mixing Cycle
Effective Production Rate = 24 tons / 1.5 min
Next, we convert the mixing cycle to hours:
Mixing Cycle in Hours = Mixing Cycle / 60
Mixing Cycle in Hours = 1.5 min / 60
Now, we calculate the plant production in tons per hour:
Plant Production = Effective Production Rate / Mixing Cycle in Hours
Plant Production = (24 tons / 1.5 min) / (1.5 min / 60)
Simplifying the expression:
Plant Production = 24 tons / (1.5 / 1.5) hours
Plant Production = 24 tons / 1 hour
Therefore, the plant production is estimated to be 24 tons per hour.
To calculate the square footage of coating required between the flange connection and the 45-degree elbow, we need the centerline distance and the diameter of the pipe. However, the given information does not include the diameter of the pipe, which is necessary to calculate the square footage.

(d.) (e.) (f.) 2s²2s+6 2 (S-1)(s² +3s+2) 2s² +s-2 2 s² (s+1) 3s-1 3 s³ (S-1)
The partial fractions for the given equations are as follows:
2s²2s+6 = (1/2) (1/s) - (1/2) (1/(s+3))2 (S-1)(s² +3s+2)
= 1/(s-1) - 1/(s+2) + 1/(s+1)2s² + s - 2
= 2(s + 1)(s - 1/2)2 s² (s+1) 3s-1
= 2/s + 1/(s+1) - 2(s-1)
Partial fraction is the representation of a complex rational function as the sum of simple rational expressions. A partial fraction can be divided into three categories, namely: proper, improper and mixed.
In the first problem, we have: 2s²2s+6
Our first step is to factor the denominator as shown below: 2(s² + s + 3)
Using partial fractions, we write: 2s²2s+6 = A/s + B/(s+3)
Let's find A and B: 2s²2s+6 = A(s+3) + B(s)2s²2s+6 = As + 3A + Bs
Comparing the coefficients of s², s and the constants, we get:A = 1/2B = -1/2
Therefore,2s²2s+6 = (1/2) (1/s) - (1/2) (1/(s+3))
Next, we consider:2 (S-1)(s² +3s+2)
Factorize the denominator as shown below:
2(s-1)(s+2)(s+1)2 (S-1)(s² +3s+2) = A/(s-1) + B/(s+2) + C/(s+1)
Now, we solve for A, B and C as follows:
2 (S-1)(s² +3s+2) = A(s+2)(s+1) + B(s-1)(s+1) + C(s-1)(s+2)
When s = 1, we have:2 (1-1)(1² + 3(1) + 2) = A(1+2)(1+1)
Therefore, A = 1
When s = -2, we have: 2 (-2-1)(-2² + 3(-2) + 2) = B(-2-1)(-2+1)
Therefore, B = -1
When s = -1, we have: 2 (-1-1)(-1² + 3(-1) + 2) = C(-1-1)(-1+2)
Therefore, C = 1
So, 2 (S-1)(s² +3s+2) = 1/(s-1) - 1/(s+2) + 1/(s+1)
In the third problem, we have: 2s² + s - 2
This is a quadratic equation. To factorize it, we find its roots using the quadratic formula, which is given as:-
b ± √(b² - 4ac)2a
Hence, we have:
s1,2 = (-b ± √(b² - 4ac))/2a
On substituting the coefficients, we have:
s1,2 = (-1 ± √(1² - 4(2)(-2)))/2(2)s1 = -1s2 = 1/2
We factorize the equation as shown below:
2s² + s - 2 = 2(s + 1)(s - 1/2)
Finally, we have:2 s² (s+1) 3s-1
This problem can be solved by using partial fractions.
We write the equation as:
2 s² (s+1) 3s-1 = A/s + B/(s+1) + C(s-1)
Solving for A, B and C, we have:
A = 2C = -2B = 1
Therefore,2 s² (s+1) 3s-1 = 2/s + 1/(s+1) - 2(s-1)
Therefore, the partial fractions for the given equations are as follows:
2s²2s+6 = (1/2) (1/s) - (1/2) (1/(s+3))2 (S-1)(s² +3s+2)
= 1/(s-1) - 1/(s+2) + 1/(s+1)2s² + s - 2
= 2(s + 1)(s - 1/2)2 s² (s+1) 3s-1
= 2/s + 1/(s+1) - 2(s-1)

The given equation is, x(t)= C0 + C1*sin(w*t+theta1) + C2*sin(2*w*t+theta2)This equation can be written as, x(t)= A0 + A1*cos(w*t) + B1*sin(w*t) + A2*cos(2*w*t) + B2*sin(2*w*t)Where, A0= 3, A1= 3, B1= 2, A2=-3, B2= 2, w=700 rad/sec.Conversion of the given equation into the standard form,x(t) = A0 + (C1/w)sin(w*t+θ1) + (C2/2w)sin(2w*t+θ2)Comparing the above equation with the standard equation, we get;A0 = 3, A1 = (C1/w), B1 = 2, A2 = (C2/2w), and B2 = 2wWe have,A1 = 3.60555 (rounded to 5 decimal places)C1/w = 3.60555C1 = w * 3.60555 = 700 * 3.60555 = 2523.8875 radians....(1)A2 = -3C2/2w = -3C2 = -2w * A2 = -2(700) * (-3) = 4200 radians....(2)Comparing the two given equations:x(t)= C0 + C1*sin(w*t+theta1) + C2*sin(2*w*t+theta2)x(t)= A0 + A1*cos(w*t) + B1*sin(w*t) + A2*cos(2*w*t) + B2*sin(2*w*t)We have, C1 = 2523.8875 radians from equation (1), and A1 = 3.60555 radians. Therefore, we can calculate θ1 using the following formula;θ1 = tan⁻¹(B1/A1) - tan⁻¹(C1/w * A1/B1) = tan⁻¹(2/3.60555) - tan⁻¹(2523.8875/700 * 3/2)≈ 56.3099°... (3)We have, C2 = 4200 radians from equation (2), and A2 = -3.
Therefore, we can calculate θ2 using the following formula;θ2 = tan⁻¹(B2/A2) - tan⁻¹(C2/2w * A2/B2) = tan⁻¹(2/(-3)) - tan⁻¹(-4200/(2*700) * (-2)/(-3))≈ -56.3099°... (4)From equation (1), we have C0 = x(t) - C1*sin(w*t+θ1) - C2*sin(2*w*t+θ2) = 3 - 2523.8875*sin(700t + 56.3099) - 4200*sin(1400t - 56.3099)Therefore, C0 ≈ 5Rounded to the nearest whole number, C0 = 5Therefore, the values of C0, C1, θ1, C2, and θ2 are;C0 = 5C1 = 2523.8875 radiansθ1 = 56.3099°C2 = 4200 radiansθ2 = -56.3099°Hence, the solution is as follows:Detailed Explanation:Given: x(t) = C0 + C1*sin(w*t+theta1) + C2*sin(2*w*t+theta2)x(t) = A0 + A1*cos(w*t) + B1*sin(w*t) + A2*cos(2*w*t) + B2*sin(2*w*t)Where A0= 3, A1= 3, B1= 2, A2= -3, B2= 2, and w= 700 rad/sec.Conversion of the given equation into the standard form,x(t) = A0 + (C1/w)sin(w*t+θ1) + (C2/2w)sin(2w*t+θ2)Comparing the above equation with the standard equation,

For the given differential equation, (a) The general solution to the given differential equation is : y(x) = c1 e^(-x/2)cos((3/2)x) + c2 e^(-x/2)sin((3/2)x) - (x/12) - 1/144. and (b) The specific solution to the given differential equation is : y(x) = (145/144) e^(-x/2)cos((3/2)x) - (1/4) e^(-x/2)sin((3/2)x) - (x/12) - 1/144.
The differential equation given is : d²y/dx² + dy/dx + 12y = x - 6 ...(1)
The general solution to this differential equation can be obtained by solving the homogeneous differential equation associated with (1).
The characteristic equation corresponding to the homogeneous differential equation is : m² + m + 12 = 0.
The roots of this equation are :
m1 = (-1 + sqrt(1 - 48))/2 = -1/2 + 3i/2 and
m2 = (-1 - sqrt(1 - 48))/2 = -1/2 - 3i/2.
Thus, the general solution to the homogeneous differential equation is :
y(x) = c1 e^(-x/2)cos((3/2)x) + c2 e^(-x/2)sin((3/2)x) ...(2)
Now we look for a particular solution to the differential equation (1).
The general solution is: y = yh + yp ...(3)
Particular solution: We try yp(x) = Ax + B.Substituting this in (1), we get : -12Ax - 12B + A - 6 = x - 6.
Comparing the coefficients, we have : A - 12B = 0 and -12A = 1.

Substituting x = 0 and y = 1 in equation (5), we get : c1 - 1/144 = 1 and -1/12 - 1/144 = 0.
Solving these two equations, we get : c1 = 145/144 and c2 = -1/4.
Substituting x = 5.144 in equation (5), we get :
y(5.144) = (145/144) e^(-5.144/2)cos((3/2)5.144) - (1/4) e^(-5.144/2)sin((3/2)5.144) - (5.144/12) - 1/144 = -0.431.

The mixed sizes method determined that a 1/2 inch or (e) 16 mm conduit is the proper size for 2- #4 AWG, T90 Nylon wires in rigid metal conduit.
The given wire sizes are 2- #4 AWG, T90 Nylon in rigid metal conduit. Let's use the mixed sizes method to determine the size of the proper conduit. The mixed sizes method is used when two or more conductors of different sizes are installed in the same conduit.
The following table lists the trade sizes of conduits and the maximum number of conductors of each size allowed in each trade size:
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|}
\hline
Trade size & 10 AWG & 8 AWG & 6 AWG & 4 AWG & 3 AWG & 2 AWG & 1 AWG & 1/0 AWG & 2/0 AWG & 3/0 AWG \
\hline
1/2 inch & 16 & -- & 5 & -- & 7 & -- & 3 & -- & 2 & 1 \

We have two #4 AWG conductors, which can fit in a 1/2 inch conduit. Using the table, the maximum number of conductors that can be installed in a 1/2 inch conduit are as follows:
10 AWG - 8 \8 AWG - -- \6 AWG - 5 \4 AWG - -- \3 AWG - 7 \2 AWG - -- \1 AWG - 3 \1/0 AWG - -- \2/0 AWG - 2 \3/0 AWG - 1 \Therefore, we can safely install two #4 AWG conductors in a 1/2 inch conduit. Therefore, the size of the proper conduit is 1/2 inch or 16 mm. Hence, option (e) is correct.
Here is the full statement. The size of the proper conduct:
a) 41mm
b) 27mm
c) 35mm
d) 21mm
e) 16mm

We have to write a Python function, des(G), that returns a pair of two lists: a list of babyfaces and a list of heels if it is possible to designate such.
The function should return none if it is impossible to designate babyfaces and heels. The Depth-First Search algorithm (DFS) can be used to identify whether or not the graph is bipartite or not. In a graph, a bipartition is a partition of the vertices into two independent sets, such that no two vertices of the same set are adjacent to each other.
Let's write the code for the given problem statement:## Let's start by writing a Python function that returns a pair of two lists: a list of babyfaces and a list of heels if it is possible to designate such.## Here, G is the input graph. This is an adjacency list-based graph representation.
