Quick Overview

This question evaluates a candidate's ability to implement an in-place, single-pass partitioning algorithm under strict interface constraints, commonly known as the Dutch National Flag problem. It tests practical application of the three-pointer swap technique to achieve O(n) time and O(1) space, assessing algorithmic reasoning within coding interviews for software engineering roles.
