Given an array ‘a’ of size ‘n’-1 with elements of range 1 to ‘n’. The array does not contain any duplicates. Your task is to find the missing number.

For example:

Input:
'a' = [1, 2, 4, 5], 'n' = 5

Output :
3

Explanation: 3 is the missing value in the range 1 to 5.

You are given a string 'S'. Your task is to check whether the string is palindrome or not. For checking palindrome, consider alphabets and numbers only and ignore the symbols and whitespaces.

Note :

String 'S' is NOT case sensitive.

Example :

Let S = “c1 O$d@eeD o1c”.
If we ignore the special characters, whitespaces and convert all uppercase letters to lowercase, we get S = “c1odeedo1c”, which is a palindrome. Hence, the given string is also a palindrome.
