There is an undirected tree where each vertex is numbered from to, and each contains a data shrubdrop.club sum of a tree is the sum of all its nodes' data values. If an edge is cut, two smaller trees are formed. The difference between two trees is the absolute value of the difference in their sums. Given a tree, determine which edge to cut so that the resulting trees have a minimal difference Estimated Reading Time: 2 mins. Cut Tree. Cut Tree.

For those who are stuck, here are hints: 1. Dont think of it as a Tree problem. Approach it as a GRAPH. 2. Use first run of DFS to compute a value (not telling what it is:p) that you think will help you solve the problem.
