/*
* Setting Bit: https://www.geeksforgeeks.org/set-k-th-bit-given-number/
*
* To set any bit we use bitwise OR (|) operator.
*
* Bitwise OR (|) compares the bits of the 32
* bit binary representations of the number and
* returns a number after comparing each bit.
*
* 0 | 0 -> 0
* 0 | 1 -> 1
* 1 | 0 -> 1
* 1 | 1 -> 1
*
* In-order to set kth bit of a number (where k is the position where bit is to be changed)
* we need to shift 1 k times to its left and then perform bitwise OR operation with the
* number and result of left shift performed just before.
