Problem statement
Write a program to take a string as input and check whether it is palindrome or not.
What is mean by palindrome string or number
A palindrome string is a string that reads the same backward as forward.
For example: madam, racecar, etc.
A palindrome is a number that remains the same when its digits are reversed.
A number is a palindrome if the reverse of that number is equal to the original number.
