WebHere we again follow the same step and subtract the node value and pass it to the left and right subtrees. Here at node 2 the sum is 4, at node 4 the sum is 4, for 11 and 6 the sum is negative. Hence we got one leaf node whose value equal to the sum at that node. Hence we say the path from leaf node 4 to root is our answer.

Web5 sep. 2015 · As can be seen, there are 15 levels to this tree (including the top most node). Therefore, there are 214 possible routes to scan in order to check for the maximum sum using brute force. As there are only 214 (16384) routes, it is possible to solve this problem by trying every route.
