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?

(Financial: credit card number validation) Credit card numbers follow certain pat-
terns. A credit card number must have between 13 and 16 digits. It must start with:
4 for Visa cards
5 for Master cards
37 for American Express cards
6 for Discover cards
In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card
numbers. The algorithm is useful to determine whether a card number is entered
correctly or whether a credit card is scanned correctly by a scanner. Credit card
numbers are generated following this validity check, commonly known as the
Luhn check or the Mod 10 check, which can be described as follows (for illustra-
tion, consider the card number 4388576018402626):
1. Double every second digit from right to left. If doubling of a digit results in a
two-digit number, add up the two digits to get a single-digit number.
4388576018402626
→ 2 * 2 = 4
→ 2 * 2 = 4
→ 4 * 2 = 8
→ 1 * 2 = 2
6 * 2 = 12 (1+ 2 = 3)
→ 5 * 2 = 10 (1+ 0 = 1)
→ 8 * 2 = 16 (1 + 6 = 7)
→ 4 * 2 = 8

- (Python programming) Write a program that incorporates an algorithm with a function that will check whether or not a string is in a valid password format with the following rules: A password must have at least ten characters.A password consists of only letters, digits and symbol(s).A password must contain at least two digits. A password must contain at least one uppercase letter A password must contain at least one special symbol Your program should continue to prompt until the user enters a valid password. Regular expressions (regex) are not allowed!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(java programming language) Write a Java program to do the following task: Assign your id number (example.. 2014299123) to an integer variable id_num Using reminder operator % on the id_num get the last 5 digits (99123) and store it in num If the num is between 0 and 30,000 (both included), display “You are in Group 1” Otherwise if the num is between 30001 and 60,000 (both included), display “You are in Group 2” Otherwise (num is between 60,001 and 99,999 (both included), display “You are in Group 3” Save your file as Q2.Javaarrow_forward

(After the character library functions are explained)arrow_forwardWhat is the output of the following code segment?arrow_forwardRewrite the following code segment using conditional operators (?/:)arrow_forward
- [SHORT ANSWER] Use Python. Using loop, if, and string methods validate the string variable password by making sure the length of the password is at least 8 characters and has at least one alphabet and one digit. Display appropriate messages as shown in the following examples (use any additional variables):arrow_forwardWrite a code to this usingarrow_forwardQ3. (Dice Rolling) Write a program that simulates the rolling of two dice. The program should use rand to roll the first die and should use rand again to roll the second die. The sum of the two values should then be calculated. [Note: Each die can show an integer value from 1 to 6, so the sum of the two values will vary from 2 to 12, with 7 being the most frequent sum and 2 and 12 being the least frequent sums.] Figure 7.26 shows the 36 possible combinations of the two dice. Your program should roll the two dice 10,000 times. Use a one-dimensional array to tally the numbers of times each possible sum appears. Print the results in a tabular format. Also, determine if the totals are reasonable (i.e., there are six ways to roll a 7, so approximately one-sixth of all the rolls should be 7). 1 2 3 4 5 1 2 4 6 7 3 4 6 7 3 4 5 7 8 9 4 7 8 9 10 7 8 10 11 7 10 11 12 Row\Col 3.arrow_forward
- Write the following function to check whether a string is a palindrome assuming letters are case-insensitive: bool isPalindrome(const string& s) Write a test program that reads a string and displays whether it is a palindrome.arrow_forwardQ5. (Find the second lowest interger number) Write a program that prompts the user to enter a set of integer numbers, and finally displays the second lowest integer number in the set. To exit from the program enter -1. Here is a sample run Enter a set of integer numbers: 3 57 928-1 The second lowest number is 3.arrow_forward4. (Prime Numbers) An integer is said to be prime if it is divisible by only 1 and itself. For example, 2, 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not. Write a function called isPrime that receives an integer and determines whether the integer is prime or not. Write a test program that uses isPrime to determine and prints all the prime numbers between 1 and 1000. Display 10 numbers per line.arrow_forward
