LeetCode 54 Spiral Matrix | Boundary Traversal Explained in Python

In this video, we solve LeetCode 54: Spiral Matrix using a clean boundary-based approach. This problem teaches one of the most important matrix traversal patterns. We learn how to move in four directions, how to shrink boundaries after every layer, and how to avoid duplicate traversal when only one row or column is left. Concepts covered: 2D matrix traversal Spiral order traversal Top, bottom, left, right boundaries Python range handling Time and space complexity Common mistakes in matrix problems We first understand the problem, then discuss the brute force idea, build the optimal approach, write pseudocode, code it in Python, dry run examples, and finally discuss critical mistakes. Problem: LeetCode 54 - Spiral Matrix Difficulty: Medium Language: Python 3 Watch till the end if you want to understand matrix problems deeply. #LeetCode #DSA #Python #CodingInterview #Matrix
