Solution: Sort Colors
Explore how to solve the Sort Colors problem efficiently by applying the Dutch National Flag algorithm. Understand using three pointers to partition an array into red, white, and blue sections in one pass, optimizing for time and space. This lesson helps you implement an in-place linear time solution using the two pointers pattern.

Statement
You are given an array nums of length n, where each element represents an object colored either red, white, or blue. The integers 0, 1, and 2 are used to represent red, white, and blue, respectively.
Sort the array in place so that all objects of the same color are grouped together, arranged in the order: red (0), white (1), and blue (2).
You must solve this problem without using any library sort function. ...
