  * algorithm to count the number of set bits in a given number

  * Subtraction of 1 from a number toggles all the bits (from right to left) till the rightmost set bit(including the
- * rightmost set bit). 
- * So if we subtract a number by 1 and do bitwise & with itself i.e. (n & (n-1)), we unset the rightmost set bit.

  * If we do n & (n-1) in a loop and count the no of times loop executes we get the set bit count.
