# Given a binary tree, find out the maximum sum of value from root to each leaf.

**Objective:** **– **Find the maximum sum leaf to root path in a Binary Tree. Means in all the paths from root to leaves, find the path which has the maximum sum.

**Input:** A binary tree

**Example:**

This solution will be divided into two parts

**Find the leaf which has the maximum sum from root.**

- Take a global variable maxLeaf and maxSum. (this maxLeaf will the node which has the maximum sum path and maxSum will the maximum sum.)
- Do the preorder traversal
- At each node, maintain a another variable sum = sum + root.data.
- When ever you reach to any leaf, check if sum>maxSum, if yes then update the maxLeaf and maxSum.

**Print the path from root to that leaf.**

Please refer this link to print the path.

**Complete Code:**

**Output**:

Maximum Sum Leaf to Root path :18 Path : 8 6 3 1
