Solution: Sort Colors
Explore how to sort an array of red, white, and blue colors by applying the two pointers technique. Understand the Dutch National Flag algorithm that efficiently rearranges elements in a single traversal with constant space. Gain the ability to implement a linear time, in-place sorting solution for similar interview problems.
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...
