 Algorithm requested (Posted on 2013-12-18)
Given an array with random odd and even integers.
Please suggest the most efficient algorithm to put all even numbers on one side and all odd numbers on the other side in this array.

Steps:
(1) convert from base 10 to base 2
(2) reverse the digits
(3) sort from smallest to largest
(4) reverse the digits
(5) convert from base 2 to base 10

Since the even numbers all end in zero (in base 2), putting the reversed binary representation in smallest to largest order puts all the even numbers at the beginning and all the odd numbers at the end
