Web Reference: In-depth solution and explanation for LeetCode 112. Path Sum in Python, Java, C++ and more. Intuitions, example walk through, and complexity analysis. Better than official and forum solutions. The problem specifically requires a root-to-leaf path, so internal nodes should not trigger a true result even if the running sum matches the target. Always verify that both left and right children are null before comparing sums. Path Sum - Given the root of a binary tree and an integer targetSum, return true if the tree has a root-to-leaf path such that adding up all the values along the path equals targetSum.
