Check whether K-th bit is set or not

Given a number n, check if the Kth bit of n is set or not.
 

Examples:

Input : n = 5, k = 1
Output : SET
5 is represented as 101 in binary and has its first bit set.

Input : n = 2, k = 3
Output : NOT SET
2 is represented as 10 in binary, all higher i.e. beyond MSB, bits are NOT SET.
