Problem:Write a program that reads a list of integers from the keyboard and creates thefollowing information.a. Finds and prints the sum and the average of the integersb. Finds and prints the largest and the smallest integerc. Prints a Boolean (true or false) if some of them are less than 20d. Prints a Boolean (true or false) if all of them are between 10 and 90The input data consist of a list of integers with a sentinel. The program mustprompt the user to enter the integers, one by one, and enter the sentinel whenthe end of the list has been reached. The prompt should look like the following: Enter the numbers with <return>(99999 to stop):The output should be formatted as shown below: The number of integers is: xxxThe sum of the integers is: xxxxThe average of the integers is: xxx.xxThe smallest integer is: xxxThe largest integer is: xxxAt least one number was < 20: <true or false>All numbers were ( 10 <= n >= 90): <true or false>

Give the index of the pivot value after the whole list below has been partitioned using the median-of-3 value as the pivot value. [93, 49, 60, 65, 40, 74, 50, 69, 58, 97, 64] Notes: • Your answer should be a single valid, non-negative, literal Python int value. For example, 123 is a valid int literal. • This is not asking for the complete quicksort. • Hint: you don't have to get everything in the exactly the right place, just the pivot value. You can do a rough partition, ensuring each value is on the appropriate side of the pivot value. • You can pre-check your answer (to check it's a valid, non-negative, literal int). Answer: (penalty regime: 10, 20, ... %) Precheck Check

Exercise 1: Write a program using the java.util.Stack data structure that prompts for an integer and reverses it: 7359 becomes 9537. Hints: Think of how base-10 works: A base-10 number is a sum of digit * 100 + digit * 101 + digit * 102, etc., where each digit in your number is that digit times a power of 10. Using that understanding, you can use modulo and integer arithemetic to get each digit and add it to a stack. Algorithm: Your number % 10 will give you the rightmost number. Example: 7359 % 10 = 9. Put the 9 on the stack. Now substract the 9 from original number: 7359 - 9 = 7350. Now take the 7350/10 to remove the zero. That is 7350 /10 = 735. Repeat the process, that is 735 % 10 = 5, put the 5 on the stack, substract the 5 and divide by 10. 730/10 = 73, use 73 % 10 to get the 3. Keep going, adding digits to the stack until you run out of numbers. When you pop the numbers off your stack, they will come off teh stack reversed. Note…
help pleeasee Create a C code that will allow the user to input a word and check whether it is a palindrome or not. Also input the reversed string of the word. Use a stack to reverse the order of a string and identify whether it is a palindrome or not. It should not be case-sensitive. Example 1: Input string: Racecar Reversed string: racecar Palindrome: Yes exampl 2: Input string:ToyotA Reversed string: atoyot Palindrome: No Note: maximum string length is 20
