To create the function square(lst), we can define it like this:
```python
def square(lst):
new_lst = [] # create an empty list to store the squared values
for num in lst:
new_lst.append(num ** 2) # square each element and add it to the new list
return new_lst # return the new list with squared values
```
This function takes in one parameter, which is a list of integers, and returns a new list with the square of each element in the original list.
For example, if we call the function with `square([1, 2, 3, 4])`, it will return `[1, 4, 9, 16]`, which is the squared version of the original list. Similarly, if we call it with `square([10, 12, 15])`, it will return `[100, 144, 225]`, which is the squared version of this list.

the big win for quicksort over mergesort is that it runs in place. true or false
Yes, the above statement is true. One of the big advantages of quicksort over mergesort is that it operates in place, meaning that it doesn't require additional memory space to sort the elements.
A divide-and-conquer algorithm is a quicksort. It operates by choosing one element from the array to serve as the "pivot," and then dividing the remaining components into two sub-arrays based on whether they are less than or greater than the pivot. It is referred to as partition-exchange sort for this reason.
Merge sort, which is also sometimes spelled mergesort, is a general-purpose, effective sorting algorithm used in computer science. The logical sequence of equal elements is identical in the input and output for the majority of implementations, which results in a stable sort.

Suppose that Malice is attempting to guess the password for a smartphone taken from Alice. Through research, Malice knows that the password is a total of 9 characters, where each character can be an English upper or lower case letter or a digit from 0 to 9 inclusive. Malice was able to obtain the first 2 characters in the password by posing as a maintenance repair worker at Alice's workplace to observe her (using social engineering), but does not have the remaining characters.
a) Showing all steps, calculate and show the password search space of the remaining portion of this password Malice is attempting to obtain. Also, explain how this password should be stored in Alice's smartphone, for best security?
The password search space for the remaining portion of the password is approximately 3.5 x 10^13 possible combinations. For best security, a strong and unique password should be used that is difficult to guess or brute-force.
The password search space for the remaining 7 characters is the total number of possible combinations of upper and lower case letters and digits raised to the power of 7. This is calculated as follows:
There are 62 possible characters for each of the 7 remaining characters (26 upper case letters + 26 lower case letters + 10 digits = 62).
Therefore, the password search space is 62^7, or approximately 3.5 x 10^13.
This password should be kept as a salted hash on Alice's smartphone for maximum security. Salt is a random value that is added to the password before hashing to make it more difficult to crack for attackers. Both the salt and the hashed value should be saved in the smartphone's memory separately. Even if an attacker has the hashed password, they will still need to know the salt value to break it.
Additionally, the hash function used should be a strong one-way hash function, such as bcrypt or script, to further increase the difficulty of cracking the password.

which term means to scramble, mix up, or change data in such a way that bad guys cannot read it; however, the person receiving the data can descramble it.
The term that describes the process of scrambling, mixing up, or changing data in such a way that it becomes unreadable to unauthorized users is called "encryption."
Encryption is a security technique that involves transforming plain text (i.e., readable data) into an unreadable format (i.e., cipher text) using an algorithm and a key. The algorithm is the mathematical formula used to transform the data, and the key is a secret code or password that is used to lock and unlock the encrypted data.
The purpose of encryption is to protect sensitive information, such as passwords, credit card numbers, and personal data, from being intercepted and read by unauthorized users. The process of encryption makes it difficult for attackers to understand the data even if they intercept it, as they would need the correct key or password to decrypt the data and make it readable.
The person or organization that receives the encrypted data can use the correct key or password to decrypt it and convert it back to its original, readable format. This process of decryption involves reversing the encryption algorithm and transforming the cipher text back to the original plain text.

Approximately how many songs could the first ipod hold?
The first iPod was released in 2001, and it had a storage capacity of 5GB. This might not seem like much today, but at the time, it was a significant amount of storage for a portable music player.
To put it into perspective, 5GB is enough to hold approximately 1,000 songs, assuming that each song is about 5MB in size. Of course, this is just an estimate, as the size of songs can vary depending on factors like the length, bit rate, and compression.It's worth noting that the first iPod wasn't the first portable music player on the market. However, it was the first one to use a hard drive instead of flash memory, which allowed it to store a lot more music. Prior to the iPod, most portable music players had a capacity of around 64MB or 128MB, which meant that they could only hold a handful of songs.Over the years, the storage capacity of iPods has increased significantly, with the latest models able to hold up to 256GB of music.

pointers are simply that are used to store the addresses of other variables. group of answer choices a. prototypes b. data types c. variables d. addresses
Pointers are a fundamental concept in programming that allow for more efficient and flexible use of memory. In simple terms, pointers are variables that hold the memory address of another variable. They are used extensively in programming languages like C and C++ to manipulate and access data in memory.
Option C is the correct answer
1)Pointers are often used to pass large data structures between functions, as passing by reference can be more efficient than passing by value. They can also be used to dynamically allocate memory during program execution, allowing for the creation and manipulation of data structures at runtime.
2)To use a pointer, we first need to declare it with a data type that matches the variable it will be pointing to. For example, if we want to create a pointer to an integer variable, we would declare it as follows:
int *ptr;
3)This declares a pointer variable called ptr that can hold the memory address of an integer variable. To initialize the pointer, we can assign it the address of an existing integer variable like this:
int num = 10;
ptr = #
Here, we assign the address of the num variable to the ptr pointer using the address-of operator (&).
4)Once we have a pointer set up, we can use it to access the value of the variable it points to using the dereference operator (*). For example, to print the value of the integer variable num using the ptr pointer, we can do this:
printf("%d\n", *ptr);
This will print the value of num, which is 10.
5)In conclusion, pointers are an essential tool for programming that allow for efficient memory management and manipulation of data structures. They are simply variables that store the addresses of other variables, and are used extensively in languages like C and C++.

What two major categories of differing site conditions exist?
The two major categories of differing site conditions are Type 1 and Type 2 differing site conditions.
Type 1 differing site conditions refer to situations where the actual site conditions encountered during construction differ materially from those indicated in the contract documents, such as geotechnical reports, drawings, or specifications. These may include unexpected soil types, underground utilities, or hidden obstructions.
Type 2 differing site conditions involve situations where the actual site conditions encountered during construction differ materially from the typical conditions ordinarily encountered and generally recognized as inherent in the type of work being performed. These could include unusual weather conditions, unexpected groundwater levels, or unanticipated rock formations.
Both categories can lead to additional costs and delays in construction projects, making it essential for contractors and owners to address them promptly and effectively.

This next problem is going to deal with checking if someone inputs a string with a few requirements. Imagine you are prompted to input a password, but the password needs to have include uppercase and a number. In order to do this, you must look at each char in the string and Booleans to indicate certain criteria are met. Since there are 3 criteria, you should have 3 Boolean variables. The rules for the password are: • Must contain at least 8 chars • Must contain 1 uppercase letter • Must contain 1 digit • There are no restrictions with lowercase letters or special chars When considering where to use Booleans, think of it as a "flag", for each criteria. If you meet the length requirement, then the flag would change from FALSE to TRUE. Once all the flags are true, you will have a valid password. Tip: The ASCII table can be used to determine the numeric value of a particular char. You may want to create ranges of these numerical values for each criteria.
The requirements that meets user's input string are length, uppercase letters, and numbers.
Specifically, the password must contain at least 8 characters, at least 1 uppercase letter, and at least 1 digit.
To check these requirements, you can use Boolean variables as "flags" for each criteria. For example, if the password contains at least 8 characters, you can set a Boolean variable to true to indicate that this criteria has been met. Similarly, if the password contains an uppercase letter or a digit, you can set other Boolean variables to true.
To determine whether a character in the password is an uppercase letter or a digit, you can use the ASCII table to find the numeric value of that character. Then, you can create ranges of these numerical values to check whether the character meets the criteria for an uppercase letter or a digit.
Once all three Boolean variables are true, you can consider the password to be valid.
Overall, this approach allows you to use Boolean variables and the ASCII table to check whether a user's input string meets certain requirements.
