WebProblem 2. Turn on k’th bit in 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 OR of this expression with n, i.e., n (1 << (k - 1)), we get a number which has all bits the same as n except the k'th bit which will be set to 1. WebBuy Don't Get Bit. $4.99.
