Solution: Sort Colors
Explore how to efficiently sort an array containing the colors red, white, and blue using the two pointers technique. This lesson helps you understand the Dutch National Flag algorithm to rearrange the array in a single pass with O(n) time and O(1) space complexity.
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...
