Solution: Sort Colors
Explore the two pointers technique to efficiently sort an array containing colors represented as 0, 1, and 2, known as the Dutch National Flag problem. Learn to organize elements in a single pass with constant space, understanding pointer manipulation and swap operations for sorting by color.
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...
