Two Pointers Explained: The Leetcode Pattern You Need

The two pointer technique is one of the most useful DSA patterns to know, especially for technical interviews where you need clean, efficient solutions fast. In this video, we break down what two pointers is, how to recognize when it applies, and how to reason about pointer movement without guessing. Then we work through multiple classic LeetCode problems in Python, coding in real time with commentary and testing each solution as we go.
