Q$-3$ Given a string, write a python function to check if it is palindrome or not. A string is said to be a palindrome if the reverse of the string is the same as the string. For example, "radar" is a palindrome, but "radix" is not a palindrome.

Note: Both "Radar" and "radar" are considered palindromes for this program.

Example $1$:

Program Prompt: Enter a keyword:

User response: 'Apple'

Program prints: 'Not a palindrome!$\text{'}$

Example $2$:

Program Prompt: Enter a keyword:

User response: 'Malayalam'

Program prints: 'Yes, this is a palindrome!$\text{'}$ eed to make exactly like examples I
