# Find value of k-th bit in binary representation

Given a number n and k (1 <= k <= 32), find value of k-th bit in binary representation of n. Bits are numbered from right (Least Significant Bit) to left (Most Significant Bit).

Examples :

```Input :  n = 13, k = 2
Output : 0
Binary representation of 13 is 1101.
Second bit from right is 0.

Input :  n = 14, k = 3
Output : 1
Binary representation of 14 is 1110.
Third bit from right is 1.
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

1) Find a number with all 0s except k-th position. We get this number using ( 1 << (k-1) ). For example if k = 3, then ( 1 << 2) gives us (00..00100).
2) Do bitwise and of above obtained number with n to find if k-th bit in n is set or not.

## C++

 `// CPP program to find k-th bit from right ` `#include ` `using` `namespace` `std; ` ` `  `void` `printKthBit(unsigned ``int` `n, unsigned ``int` `k) ` `{ ` `     ``cout << (n & (1 << (k-1))); ` `} ` ` `  `int` `main() ` `{ ` `  ``unsigned ``int` `n = 13, k = 2; ` `  ``printKthBit(n, k); ` `  ``return` `0; ` `} `

## Java
