Solution: Sort Colors
Explore the two pointers technique to efficiently sort an array containing three colors represented by 0, 1, and 2. Understand the algorithm that sorts the array in a single traversal without extra space, focusing on swapping elements and pointer adjustments.

Statement
Given an array, colors, which contains a combination of the following three elements:
0 (Representing red)
1 (Representing white)
2 (Representing blue)
Sort the array in place so that the elements of the same color are adjacent, and the final order is: red (0), then white (1), and then blue (2).
Note: You are not allowed to use any built-in sorting functions. The goal is to solve this efficiently without extra space.
Constraints:
colors.length...
