Given an array with n objects colored red, white or blue, sort them so that objects of the same color are adjacent, with the colors in the order red, white and blue.

Here, we will use the integers 0, 1, and 2 to represent the color red, white, and blue respectively.

This problem is trivial when using two-pass counting sort: first pass count the numbers of each color, and then assign each element in array into corresponding regions in the array in the second pass.
