Check if the bit is set
Given an integer
n and a number p which is a power of 2, you are asked to find out if the bit corresponding to p is set to 1 in n.Input
The input contains two integers
n (1 ≤ n ≤ ) and p (1 ≤ p ≤ ).Output
The program should print
Yes if the corresponding bit is set and No otherwise.Examples
Input | Output |
9 8 | Yes |
9 4 | No |
9 1 | Yes |
311 4 | Yes |
311 8 | No |
Explanation
- 9 → 1001, 8 → 1000 ⇒ the most significant bit is set which corresponds to 8
- 9 → 1001, 4 → 100 ⇒ the 3rd (from the right) bit is not set
- 9 → 1001, 1 → 1 ⇒ the least significant bit is set which corresponds to 1
- 311 → 100110111, 4 → 100 ⇒ the 3rd (from the right) bit is set
- 311 → 100110111, 8 → 1000 ⇒ the 4th (from the right) bit is not set
