Check weather K-th bit is set or not.

Given a number N and a bit number K, check if Kth index bit of N is set or not. A bit is set if it is 1.
Position of set bit '1' should be indexed starting with 0 from LSB side in binary representation of the number.
Note - Index is starting from 0.

Example-1 
  Input  : N = 4 , K = 0
  Output : No

  Explanation: Binary representation of 4 is 100, in which 0th index bit from LSB is not set.
  So, return false.

Example-2
  Input : N = 4 , K = 2
  Output : Yes

  Explanation: Binary representation of 4 is 100, in which 2nd index bit from LSB is set.
  So, return true.

Example-3
  Input : N = 500 , K = 3
  Output : No

  Explanation: Binary representation of 500 is 111110100, in which 3rd index bit from LSB is not set.
  So, return false.

Your task:
You don't have to read input or print anything. Your task is to complete the 
function checkKthbit() that takes n and k as parameters and returns either true(if kth bit is set)
or false (if kth bit is  not set).
