Solution: Sort Colors
Explore how to efficiently sort an array containing red, white, and blue colors using the two pointers method. Understand the Dutch National Flag algorithm to rearrange elements in a single pass without extra space. This lesson helps you implement swaps and pointer updates to solve the problem in linear time and constant space.
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...
