71. Sort Colors

MediumTwo Pointers

Given an array nums with n objects colored red, white, or blue, sort them in-place so that objects of the same color are adjacent, with the colors in the order red, white, and blue. We will use the integers 0, 1, and 2 to represent the color red, white, and blue, respectively. You must solve this problem without using the library's sort function.

Examples

Input: [2,0,2,1,1,0]

Output: [0,0,1,1,2,2]

Explanation: Public test case for Sort Colors

Constraints

n == nums.length
1 <= n <= 300
nums[i] is either 0, 1, or 2.

Run checks all cases above. Submit evaluates all test cases.
