* returns a number after comparing each bit:
*
* 0 & 0 -> 0
* 0 & 1 -> 0
* 1 & 0 -> 0
* 1 & 1 -> 1
*
* For every odd numbers, the last binary bit will be 1
* and for even numbers, the last binary bit will be 0.
*
* As the number is compared with one, all the
* other bits except the last will become 0. The
* last bit will be 0 for even numbers and 1 for
* odd numbers.
