[tex](e)\ "1"23"4"30"7"17[/tex]
Explanation:
Required
Evaluate each expression
The simple rules to follow are:
(1) All expressions in bracket will be evaluated based on its data type
(2) Divisions will return only integer values
(3) Integers immediately after string values will be concatenated (not added)
So, the results are as follows:
[tex](a)\ 4 + 1 + 9 + "." + (-3 + 10) + 11 / 3[/tex]
Evaluate till a string is encountered
[tex]4 + 1 + 9 = 14[/tex]
Followed by "."
Then:
[tex](-3 + 10) = 7[/tex]
[tex]11/ 3 = 3[/tex]
[tex]"." + (-3 + 10) + 11/3 = "."73[/tex] -- because expressions after string operations are concatenated.
So, we have:
[tex]4 + 1 + 9 + "." + (-3 + 10) + 11 / 3 = 14"."43[/tex]
[tex](b)\ 8 + 6 * -2 + 4 + "0" + (2 + 5)[/tex]
Evaluate till a string is encountered
[tex]8 + 6 * -2 + 4 =0[/tex]
[tex]"0" + (2 + 5) ="0"7[/tex]
So, we have:
[tex]8 + 6 * -2 + 4 + "0" + (2 + 5) = 0"0"7[/tex]
[tex](c)\ 1 + 1 + "8 - 2" + (8 - 2) + 1 + 1[/tex]
Evaluate till a string is encountered
[tex]1 + 1 = 2[/tex]
[tex]"8 - 2" + (8 - 2) + 1 + 1 = "8 - 2"611[/tex]
So, we have:
[tex]1 + 1 + "8 - 2" + (8 - 2) + 1 + 1 = 2"8 - 2"611[/tex]
[tex](d)\ 5 + 2 + "(1 + 1)" + 4 + 2 * 3[/tex]
Evaluate till a string is encountered
[tex]5 + 2 =7[/tex]
[tex]"(1 + 1)" + 4 + 2 * 3 = "(1 + 1)"46[/tex] --- multiply 2 and 3, then concatenate
So, we have:
[tex]5 + 2 + "(1 + 1)" + 4 + 2 * 3= 7"(1 + 1)"46[/tex]
[tex](e)\ "1" + 2 + 3 + "4" + 5 * 6 + "7" + (8 + 9)[/tex]
Since a string starts the expression, the whole expression will be concatenated except the multiplication and the expressions in bracket.
So, we have:
[tex]"1" + 2 + 3 + "4" + 5 * 6 + "7" + (8 + 9) = "1"23"4"30"7"17[/tex]

How many fingers do you need to type floor
Answers
Answer:
About 0-1 fingers at minimum
Explanation:
you can type with your toes/elbow as well. Any body part really.
To type the word "floor" on a regular keyboard layout, you would generally need six fingers: three on your left hand and three on your right.
Your index finger (usually used for the "F" key) on your left hand would be utilised for the letter "f." Your middle finger (which is normally used for the "D" key) would be utilised for the letter "l."
Finally, your ring finger (which is normally used for the "S" key) would be utilised for the letter "o."
Your index finger (usually used for the "J" key) on your right hand would be utilised for the letter "o." Your middle finger (which is normally used for the "K" key) would be utilised for the second letter "o."
Finally, your ring finger (which is normally used for the "L" key) would be utilised for the letter "r."
Thus, on a typical keyboard layout, you would type the word "floor" with three fingers from each hand.

The code snippet created is supposed to take any input number from the user (positive or negative) and print it to the console if it is less than 0. In this code the IF statement does not need an else clause and will work regardless. The System.out.println() statement does not need to be inside braces since it is a simple one line statement.

Explanation:
Given
The above code segment
Required
What is true about the code segment
Analyzing the options, we have:
(1) Wrong statement because there is no else clause
The above statement is not a requirement for an if statement to be valid; i.e. an if statement can stand alone in a program
Hence, (1) is false
(2) The print statement must be in { }
There is only one statement (i.e. the print statement) after the if clause. Since the statement is just one, then the print statement does not have to be in {} to be valid.
Hence, (2) is false
(3) number is displayed, if input is 0
In the analysis of the program, we have: number <=0
i.e. the if statement is true for only inputs less than 0 or 0.
Hence, number will be printed and (3) is false
(4) number is displayed for positive inputs
The valid inputs have been explained in (3) above;
Hence, (4) is false.

*11.13 (Remove duplicates) Write a method that removes the duplicate elements from
an array list of integers using the following header:
public static void removeDuplicate(ArrayList list)
Write a test program that prompts the user to enter 10 integers to a list and displays
the distinct integers separated by exactly one space. Here is a sample run:
Enter ten integers: 34 5 3 5 6 4 33 2 2 4
The distinct integers are 34 5 3 6 4 33 2
Answers
Answer:
The program in Java is as follows:
import java.util.*;
public class Main {
public static void removeDuplicate(ArrayList<Integer> list){
ArrayList<Integer> newList = new ArrayList<Integer>();
for (int num : list) {
if (!newList.contains(num)) {
newList.add(num); } }
for (int num : newList) {
System.out.print(num+" "); } }
public static void main(String args[]){
Scanner input = new Scanner(System.in);
ArrayList<Integer> list = new ArrayList<Integer>();
System.out.print("Enter ten integers: ");
for(int i = 0; i<10;i++){
list.add(input.nextInt()); }
System.out.print("The distinct integers are: ");
removeDuplicate(list);
}}
Explanation:
This defines the removeDuplicate function
public static void removeDuplicate(ArrayList<Integer> list){
This creates a new array list
ArrayList<Integer> newList = new ArrayList<Integer>();
This iterates through the original list
for (int num : list) {
This checks if the new list contains an item of the original list
if (!newList.contains(num)) {
If no, the item is added to the new list
newList.add(num); } }
This iterates through the new list
for (int num : newList) {
This prints every element of the new list (At this point, the duplicates have been removed)
System.out.print(num+" "); } }
The main (i.e. test case begins here)
public static void main(String args[]){
Scanner input = new Scanner(System.in);
This declares the array list
ArrayList<Integer> list = new ArrayList<Integer>();
This prompts the user for ten integers
System.out.print("Enter ten integers: ");
The following loop gets input for the array list
for(int i = 0; i<10;i++){
list.add(input.nextInt()); }
This prints the output header
System.out.print("The distinct integers are: ");
This calls the function to remove the duplicates
removeDuplicate(list);

double nickels = 0.05;
double pennies = 0.01;
Scanner in = new Scanner(System.in);
System.out.println("Enter Change Value: ");
double change = in.nextDouble();
int numDollars, numQuarters, numDimes, numNickels, numPennies;
double newChange;
numDollars = (int) (change / dollars);
newChange = change % dollars;
numQuarters = (int) (newChange / quarters);
newChange = newChange % quarters;
numDimes = (int) (newChange / dimes);
newChange = newChange % dimes;
numNickels = (int) (newChange / nickels);
newChange = newChange % nickels + 0.001;
numPennies = (int) (newChange / pennies);
newChange = newChange % pennies;
System.out.println("Minimum Num of Coins needed: ");
if (numDollars != 1) {
System.out.println(numDollars + " Dollars");
} else {
System.out.println(numDollars + " Dollar");

def swap(number1,number2):
number1,number2 = number2,number1
return number1, number2
first = int(input("First: "))
second = int(input("Second: "))
print("You input the numbers as ",first,"and",second)
first,second= swap(first,second)
print("After swapping\nFirst: ",first,"\nSecond:",second)
Explanation:
This defines the function
def swap(number1,number2):
This swaps the numbers
number1,number2 = number2,number1
This returns the swapped numbers
return number1, number2
The main begins here
This gets input for first
first = int(input("First: "))
This gets input for second
second = int(input("Second: "))
Print the number before swapping
print("You input the numbers as ",first,"and",second)
This swaps the numbers
first,second= swap(first,second)
This prints the numbers after swapping
print("After swapping\nFirst: ",first,"\nSecond:",second)
Write the code to replace only the first two occurrences of the word second by a new word in a sentence. Your code should not exceed 4 lines. Example output Enter sentence: The first second was alright, but the second second was long.
Enter word: minute Result: The first minute was alright, but the minute second was long.
Answers
Answer:
Explanation:
The following code was written in Python. It asks the user to input a sentence and a word, then it replaces the first two occurrences in the sentence with the word using the Python replace() method. Finally, it prints the new sentence. The code is only 4 lines long and a test output can be seen in the attached image below.
sentence = input("Enter a sentence: ")
word = input("Enter a word: ")
replaced_sentence = sentence.replace('second', word, 2);
print(replaced_sentence)
Select the true statement about network protocols.
A. Communication cannot take place unless the protocol is executed in the same way on all devices.
B. One function of a protocol is to decompress data when it is delivered to the receiving computer.
C. Using a protocol other than TCP/IP can result in data loss.
D. Computers that are distributed across a large geographic area need a special protocol to resolve errors.
Answers
The statement that is true about network protocols is that:
Using a protocol other than TCP/IP can result in data loss.What are network protocols?A network protocol is a system of principles that governs how data is delivered between devices on the same network.
Primarily, it enables linked devices to interact with one another despite variations in internal operations, architecture, or design.
The way this is done is true the use of Transmission-control protocol/Internet protocol (TCP/IP).
TCP/IP is the primary protocol or communication language of the Internet. Therefore, using a protocol other than TCP/IP can result in data loss.

Assume that an O(log2N) algorithm runs for 10 milliseconds when the input size (N) is 32. What input size makes the algorithm run for 14 milliseconds
Answers
Answer:
An input size of N = 128 makes the algorithm run for 14 milliseconds
Explanation:
O(log2N)
This means that the running time for an algorithm of length N is given by:
[tex]F(N) = c\log_{2}{N}[/tex]
In which C is a constant.
Runs for 10 milliseconds when the input size (N) is 32.
This means that [tex]F(32) = 10[/tex]
So
[tex]F(N) = c\log_{2}{N}[/tex]
[tex]10 = c\log_{2}{32}[/tex]
Since [tex]2^5 = 32, \log_{2}{32} = 5[/tex]
Then
[tex]5c = 10[/tex]
[tex]c = \frac{10}{5}[/tex]
[tex]c = 2[/tex]
Thus:
[tex]F(N) = 2\log_{2}{N}[/tex]
What input size makes the algorithm run for 14 milliseconds
N for which [tex]F(N) = 14[/tex]. So
[tex]F(N) = 2\log_{2}{N}[/tex]
[tex]14 = 2\log_{2}{N}[/tex]
[tex]\log_{2}{N} = 7[/tex]
[tex]2^{\log_{2}{N}} = 2^7[/tex]
[tex]N = 128[/tex]
An input size of N = 128 makes the algorithm run for 14 milliseconds
