In this tutorial, I have explained binary tree root to leaf path sum solution using recursion and also explained it's java code.

Path Sum LeetCode Solution. Given a binary tree and a sum, Determine if the tree has a root-to-leaf path such that adding up all the values along the path equals the given sum.

If path is found then return true else return false.

Note: Any node whose left and right children is null is known as leaf node.
