LeetCode Problem

Sort Colors

Array Two Pointers Sorting

Problem Statement

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. Example 1: Example 2: Constraints: Follow up: Could you come up with a one-pass algorithm using only constant extra space?
