A bitwise operation is an operation that manipulates individual bits in a binary representation of a number. Common bitwise operations include AND (&), OR ... 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.
