CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?

Problem Description:
In the Whimsical Library, each book is enchanted with a magical code to ensure the
protection of knowledge. The validation process for these magical codes involves a
combination of mathematical spells.
The validation process is described as follows:
Take the sum of the digits at odd positions from left to right.
Take the sum of the squared digits at even positions from left to right.
If the absolute difference between the results from step 1 and step 2 is a prime
number, the book code is considered valid; otherwise, it is invalid.
Example 1:
Consider the magical book code 86420137.
Step 1. Take the sum of the digits at odd positions from left to right.
8+4+0+3=15
Step 2. Take the sum of the squared digits at even positions from left to right.
6^2+2^2+1^2+7^2=36+4+1+49 = 90
Step 3. If the absolute difference between the results from step 1 and step 2 is a prime
number.
115-901 75 (not a prime number)
Book code 86420137 is invalid.
Example 2:
Now, let's examine the…
1. Can main be called recursively? Write a simple program that counts and shows the number of times the
recursive main is called till infinity. (write very short code)
2. Write a program that converts integer Fahrenheit temperatures from 0 to 212 degrees to floating-point
Celsius temperatures with 3 digits of precision. Perform the calculation using the formula
5x(Fahrenheit- 32)
Celsius =
The output should be printed in two right-justified columns of 10 characters each, and the Celsius
temperatures should be preceded by a sign for both positive and negative values.

- 1) Simple Calculator: In Python, implement a simple calculator that does the following operations: summation, subtraction, multiplication, division, sqrt, power, natural log and abs. a) Follow the instructions below: To work with the calculator, the user is asked to enter the first number, then the operation, and finally, a second number if required. Your code has to recognize the need for the second number and ask for it if required. After performing one operation, the calculator prints the output of the operation. After performing one operation, the calculator must not exit. It has to start again for the next operation. The calculator will be closed if the user writes 'e' as any input. Use functions to perform the operations and the appropriate conditions to prevent common errors such as entering characters as one of the numbers etc. b) Run your code and provide the results for at least one example per operation. - -arrow_forward6. Sum of Numbers Design a function that accepts an integer argument and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 50 is passed as an argument, the function will return the sum of 1, 2, 3, 4, . . . 50.

Each player chooses a secret code of 4 digits from 0 – 9. The digits must be all different. The goal of the game is for each player to guess the other player's secret code. The players in turn present their guesses to the opponents. The opponents respond by telling the players: 1. The number of bulls, i.e. the number of matching digits in their right positions, and 2. The number of cows, i.e. the number of matching digits but in different positions. ### Requirements The main goal of this assignment is to develop the bulls and cows game that allows a single player to play interactively against the computer. The game stores two secret codes, one from the player and one from the computer. The player and the computer will try to guess each other’s secret code. Both the player and the computer only have seven attempts for guessing the secret code. If the player enters invalid…arrow_forward

At the end of each trading day, the company would like to generate and post the listing of its stocks so that investors can see how their holdings performed that day. We assume that the company invests in, say, 10 different stocks. The desired output is to produce two listings, one sorted by stock symbol and another sorted by percent gain from highest to lowest.The input data is provided in a file in the following format:symbol openingPrice closingPrice todayHigh todayLowprevClose volumeFor example, the sample data is:MSMT 112.50 115.75 116.50 111.75 113.50 6723823CBA 67.50 75.50 78.75 67.50 65.75 378233...

The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east). The height (in metres) of each tree is an integer between 1 and N × N, inclusive. Magically, the height of all trees is unique. Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column. Similarly, Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row. A tree X is visible if all other trees in front of the tree X are shorter than the tree X. For example, let N = 3 and the height (in metres) of the trees are as follows6 1 87 5 32 9 4 On the first column, Bunga can see two trees, as the tree on the third row is obstructed by the other trees.

We will assume that the pool is rectangular and the depth is uniform. All input values in this program will be integers. Prompt the user to enter the pool dimensions - length, width, and depth (unit: feet) - as well as the rate at which water can be put into the pool (unit: gallons per minute). Using these values, calculate and display the time (in minutes) needed to fill the pool from completely empty to completely full. Note: you should calculate the volume of the pool (as cubic feet) and then determine the rate (in cubic feet per minute) that water can be put into the pool. Assume that there are 7.48 gallons in one cubic foot. Your program should run like the examples shown below: Enter pool dimensions Length: 10 Width: 8 Depth: 7 Water entry rate: 14 The pool will fill completely in 299.2 minutesarrow_forward
- Program - python A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consumed in a day. Then, she calculates the number of calories that result from the fat, using the following formula: calories from fat = fat grams x 9. Next, she calculates the number of calories that result from the carbohydrates, using the following formula: calories from carbs = carb grams x 4. Write a program that will make these calculations. Your program should use two separate functions to calculate fat and carb calories. Write a 3rd function that is called from main to capture user input and call the others.arrow_forwardExercise 1: (Design of algorithm to find greatest common divisor) In mathematics, the greatest common divisor (gcd) of two or more integers is the largest positive integer that divides each of the integers. For example, the gcd of 8 and 12 is 4. Why? Divisors of 8 are 1, 2, 4, 8. Divisors of 12 are 1, 2, 4, 6, 12 Thus, the common divisors of 8 and 12 are 1, 2, 4. Out of these common divisors, the greatest one is 4. Therefore, the greatest common divisor (gcd) of 8 and 12 is 4. Write a programming code for a function FindGCD(m,n) that find the greatest common divisor. You can use any language of Java/C++/Python/Octave. Find GCD Algorithm: Step 1 Make an array to store common divisors of two integers m, n. Step 2 Check all the integers from 1 to minimun(m,n) whether they divide both m, n. If yes, add it to the array. Step 3 Return the maximum number in the array.arrow_forwardQ2) (Perfect Numbers) An integer number is said to be a perfect number if its factors, including 1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 = 1 + 2 + 3. Write a function perfect that determines if parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1 and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect. Challenge the power of your computer by testing numbers much larger than 1000.arrow_forward
