WebFeb 28, 2024 · The idea is to use bitwise <<, & and ~ operators. Using the expression “~(1 << (k – 1))“, we get a number that has all bits set, except the kth bit. If we do bitwise & of this expression with n, we get a number that has all bits the same as n except the kth bit which is 0. Below is the implementation of the above idea. WebFeb 27, 2024 · 2. Using Bitwise AND operator: The idea is to check whether the last bit of the number is set or not. If last bit is set then the number is odd, otherwise even. As we know bitwise AND Operation of the Number by 1 will be 1, If it is odd because the last bit will be already set. Otherwise, it will give 0 as output.
