WebCheck if k’th bit is set for a number Practice this problem The idea is to use bitwise << and & operators. Using the expression 1 << (k - 1), we get a number with all bits 0, except the k'th bit. If we do bitwise AND of this expression with n, i.e., n & (1 << (k - 1)), any non-zero value indicates that its k'th bit is set.
