Question 1
Write a program that asks the user to enter the number of passengers in an airplane and the
weight of baggage for these passengers. Your program should then print the average weight
of all baggage; it should also print the weights in reverse order.
Sample run:
Enter the number of passengers in the airplane: 8
Enter the weights of 8 baggage: 16 45 60 13 24 29 50 30
The average weight of all baggage is 33.375
The entered weights in reverse order are 30 50 29 24 13 60 45 16
A palindromic number is a number that is the same when written forwards or backwards.
The first few palindromic numbers are therefore are:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 323
Input a number from the user.
Write a program that reverses the digits of a number.
Use this program to find if the number is a palindrome.
Print if the number is palindrome or not.
Create a different version of the program that:
Takes a 3-digit number and generates a 6-digit number with the 3-digit number repeated, for example, 391 becomes 391391. The rule is to multiply the 3-digit number by 7*11*13.
Takes a 5-digit number and generates a 10-digit number with the 5-digit number repeated, for example, 49522 becomes 4952249522. The rule is to multiply the 5-digit number by 11*9091.
Times 11: A two-digit number can be easily multiplied by 11 in one's head simply by adding the digits and inserting that sum between the digits. For example, 43 * 11 has the resulting digits of 4, 4+3, and 3, yielding 473. If the sum between the digits is greater than 9, then the 1 is carried to the hundreds place. Complete the below program.

- Given the sample code above in generating a random number. Create a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 13. The computer's choice is displayed. 4. A winner is selected according to the following rules: a.

- Three numbersa. Write a program that reads three numbers and prints “all the same” if they are allthe same, “all different” if they are all different, and “neither” otherwise.b. Write a program that reads three numbers and prints “increasing” if they are inincreasing order, “decreasing” if they are in decreasing order, and “neither”otherwise. Here, “increasing” means “strictly increasing”, with each value largerthan its predecessor. The sequence 3 4 4 would not be considered increasing.c. Repeat part b. but before reading the numbers, ask the user whetherincreasing/decreasing should be “strict” or “lenient”. In lenient mode, thesequence 3 4 4 is increasing and the sequence 4 4 4 is both increasing anddecreasingarrow_forwardAirline companies apply baggage restrictions for their passengers. An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right.

- /*code Kth Largest Factor A positive integer d is said to be a factor of another positive integer N if when N is divided by d, the remainder obtained is zero. For example, for number 12, there are 6 factors 1, 2, 3, 4, 6, 12. Every positive integer k has at least two factors, 1 and the number k itself.Given two positive integers N and k, write a program to print the kth largest factor of N. Input Format: The input is a comma-separated list of positive integer pairs (N, k). Output Format: The kth highest factor of N. If N does not have k factors, the output should be 1.
