Introduction to XOR
The Bitwise XOR operator is denoted by ^. When an XOR gate is given with 2 inputs, the corresponding outputs will be: If two input bits are different, the output is 1. In all other cases, it is 0.
In the kth bit set/unset problem, we first write the algorithm, then some pseudocode, and then implement the solution.
This problem is similar to the last lesson we discussed. If you need a clue, return to the previous lesson to further your understanding.
In the kth bit set/unset problem, we need to write a program that checks whether the kth bit of a number is 1 or 0.
