This is using Python can you please explain to me in detail this is for study guide

1. Write a program that takes in a string input and determines if the string is a

palindrome (spelled the same forward and backward).

2.

n! means n (n1) ... 3 2 1. For example, 10! = 10 9 ... 3 2 1 =

3628800, and the sum of the digits in the number 10! is 3 + 6 + 2 + 8 + 8 + 0 + 0 = 27.

Find the sum of the digits in the number 100!. Use the 100nums.txt file to help you

with this calculation.

3. If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6

and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5

below 1000. Use the 1000nums.txt file to help you with this calculation.
