Though CPUs, and computer hardware in-general, are not the main focus of this course, it can be useful to know a thing or two about computer hardware. The CPU (Central Processing Unit) is generally the piece of hardware that carries out the instructions of the python programs that you run in this class.
In this short PA, you will write a program that takes a few input values related to CPU performance. The program should determine whether or not the specified CPU is within one of four categories: high-performance, medium-performance, low-performance, and in need of an upgrade. Name the file cpu.py. Shown below is an example of the program prompting the user for three inputs, and then printing out the corresponding CPU performance category:
Press ENTER or type command to continue Enter CPU gigahertz: 2.7 Enter CPU core count: 2 Enter CPU hyperthreading (True or False): False That is a low-performance CPU
The program should spit out one of 4 strings:
How you determine which to print out should be based on the below tables:
If the CPU has hyperthreading
performance level | min GHz | min cores |
high-performance | 2.7 | 6 |
medium-performance | 2.4 | 4 |
low-performance | 1.9 | 2 |
If the CPU does not have hyperthreading
performance level | min GHz | min cores |
high-performance | 3.2 | 8 |
medium-performance | 2.8 | 6 |
low-performance | 2.4 | 2 |
There’s also one “special-case” rule: If a CPU has 20 or more cores, regardless of the other stats, it should be considered high-performance.
Examples
Below are several examples of program runs. There will be more tests on Gradescope.
Enter CPU gigahertz: 2.0 Enter CPU core count: 8 Enter CPU hyperthreading (True or False): True That is a low-performance CPU.
Enter CPU gigahertz: 4.0 Enter CPU core count: 6 Enter CPU hyperthreading (True or False): False That is a medium-performance CPU.

Implement the following functions. Each function deals with null terminated C-strings. You can assume that any char array passed into the functions will contain valid, null-terminated data. Your functions must have the signatures listed below.
1. This function returns the last index where the target char can be found in the string. it returns -1 if the target char does not appear in the string. For example, if s is “Giants” and target is ‘a’ the function returns 2.
int lastIndexOf(char *s, char target)
2. This function alters any string that is passed in. It should reverse the string. If “flower” gets passed in it should be reversed in place to “rewolf”. To be clear, just printing out the string in reverse order is insufficient to receive credit, you must change the actual string to be in reverse order.
void reverse(char *s)
3. This function finds all instances of the char ‘target’ in the string and replaces them with ‘replacementChar’. It also returns the number of replacements that it makes. If the target char does not appear in the string it returns 0 and does not change the string. For example, if s is “go giants”, target is ‘g’, and replacement is ‘G’, the function should change s to “Go Giants” and return 2.
int replace(char *s, char target, char replacementChar)
4. This function returns the index in string s where the substring can first be found. For example if s is “Skyscraper” and substring is “ysc” the function would return 2. It should return -1 if the substring does not appear in the string.
int findSubstring(char *s, char substring[])
5. This function returns true if the argument string is a palindrome. It returns false if it is not. A palindrome is a string that is spelled the same as its reverse. For example “abba” is a palindrome. So is “hannah”, “abc cba”, and “radar”.
bool isPalindrome(char *s)
Note: do not get confused by white space characters. They should not get any special treatment. “abc ba” is not a palindrome. It is not identical to its reverse.
6.This function should reverse the words in a string. Without using a second array. A word can be considered to be any characters, including punctuation, separated by spaces (only spaces, not tabs, \n etc.). So, for example, if s is “The Giants won the Pennant!” the function should change s to “Pennant! the won Giants The”.
void reverseWords(char *s)
Requirements
- You may use strlen(), strcmp(), and strncpy() if you wish, but you may not use any of the other C-string library functions such as strstr(), strncat(), etc.
- You will not receive credit for solutions which use C++ string objects, you must use C-Strings (null-terminated arrays of chars) for this assignment.

In this assignment, you will be implementing a slot machine that you find in casinos. A slot machine has certain number of reels which spin to produce one of a fixed set of symbols (e.g. flowers, bells) randomly when the user pulls a lever. The user needs to insert certain number of currency units as wager into the slot machine before pulling the lever. We refer to these currency units as “wagerUnitValue”. For example in slot machines with quarter (25 cents) as wagerUnitValue , user needs to insert one or more quarters while in dollar slot machines where wagerUnitValue = 100, user needs to insert one or more dollars as wager before pulling the lever. The user will receive a payout based on the matching of symbols on the reels. In a real slot machine there is a payout table which specifies the payout for certain combinations of symbols on the reels. In this assignment, you will instead be implementing simple payout rules based on number of matched symbols.
I have provided a skeletal implementation of a slot machine to help you get started (Check Moodle). Do not change class name, enum type or function signatures. You can however add some variables as needed. Specifically implement the following functions: (a) SlotMachine class constructor which has the following parameters: (i) numReels, (ii) odds array with one entry per symbol indicating probability of getting the symbol in a reel and (iii) wagerUnitValue in cents. (b) getSymbolForAReel() – use Math.random() to generate a random number between 0 and 1 and then use the odds array to generate a symbol randomly. (c) calcPayout() – calculate and return payout value for the given symbols on the reels; use the rules provided in the comments section of the function (d) pullLever() – this function simulates user pulling lever in the slot machine after inserting a wager. First use the function in (b), to generate symbol for each reel and then use the function in (c) to calculate the payout. You can assume that the symbols on the reels appear as independent random events. You need to print the reel symbols in a line followed by the payout in dollar format in another line. (e) getPayoutPercent() – you need to keep track of total wager given by the user as well as total payout provided to the user; this function calculates the total payout as a percent of the total wager value. (f) reset() – clears the total wager and total payout value for fresh calculation of payout percent. Submit only the SlotMachine.java file with your name added in comments section. You can use the main() function to test your program but it is not graded. The test program used for grading will call the class functions (a)-(f) directly.

Create a testbench in Verilog for the following module (logic). Verify the testbench works in your answer. I'll upvote correct answers.
This module does the following. The algorithm takes an input between 0 and 255 (in unsigned binary and counts the number of ones in each number (ex. 01010101 has 4 ones). Then the output would be 00000100 (4 in binary because there are 4 ones.
The test bench would need to verify the inputs and outputs of each number. Test 5 different numbers and ensure the output is expected for the input.
module logic(
input [7:0] A, //input is between 0-255, so 8
bits.
output reg [3:0] ones // 0-3 because, at max there can
be 8 ones. As, 8 can be represented in 3 bits.
);
integer i;// declaration of vailable i

begin
ones = 0; //initialize count variable.
for(i=0;i<8;i=i+1) //Iterate all
