WebPython program to check if kth bit of a number is set or not. So let’s see the input and corresponding output for better understanding: Input : num = 9, k = 1 Output: Set. 9 in bit representation is 1001, hence its 1st bit is set. Method-1: We can check whether kth bit of a number is set or not with the help of left shift operator. Algorithm: edge created passwordsWebReturn the k th bit in S n. It is guaranteed that k is valid for the given n. Example 1: Input: n = 3, k = 1 Output: "0" Explanation: S 3 is " 0 111001". The 1 st bit is "0". Example 2: Input: n = 4, k = 11 Output: "1" Explanation: S 4 is "0111001101 1 0001". The 11 th bit is "1".
