Find the maximum sum leaf to root path in a Binary Tree

WebApproach. The approach is pretty simple. We can check that if at a certain point, the value of a node is what we need, and it is a leaf as well. Then, we can conclude that a path exists from root to this point having target sum. So, it is intuitive that as we recursively jump to any child, we must pass on the remaining sum to complete the target. WebCan you solve this real interview question?

WebPath Sum II LeetCode Solution – Given the root of a binary tree and an integer targetSum, return all root-to-leaf paths where the sum of the node values in the path equals targetSum. Each path should be returned as a list of the node values, not node references. A root-to-leaf path is a path starting from the root and ending at any leaf node. WebThe sum for a root to leaf path is the sum of all intermediate nodes, the root & leaf node, i.e., sum of all the nodes on the path. Like for the first path in the above example the root to leaf path sum is 22 (8+5+9) Our program must be to determine whether the given sum is same as anythe root to leaf path sum.
