Solution: Sort Colors
Explore how to sort an array containing red, white, and blue elements using the two-pointer approach. Understand how to rearrange the colors in a single pass with constant space, applying the Dutch National Flag algorithm for efficient in-place sorting without built-in functions.
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...
