BackTracking Visually Explained | Combination Sum Leetcode 39

In this video, we’ll explore the concept of backtracking through a classic problem—LeetCode’s Combination Sum. Starting with a simple tree visualization, we’ll break down the logic step-by-step to understand how backtracking explores possibilities, prunes dead ends, and finds valid solutions. Along the way, we’ll discuss how this technique differs from depth-first search and write clean, efficient Python code to solve the problem. Whether you’re preparing for coding interviews or just love problem-solving, this video will give you a solid understanding of backtracking’s power and elegance.

I liked the video, but it would be even better if you could include an explanation of how the recursion works on one side, with a tree visualization on the other side
