Zigzag Arrangement
Given an array with possible repeating elements you have to rearrange such that elements are alternatively decreasing and increasing (strict increase/decrease). For example, suppose the given array is 1 1 2 3 4 5 one possible answer would be 2 1 3 1 5 4. Assumption: Solution do exist for any given input. Hint: Try to avoid sorting.
