The Tree Hackerrank Solution Python: Cut

We root at 1 and compute subtree sums:

return min_diff

The intuitive but naive approach is:

The crucial observation is:

Practice similar problems on HackerRank like "Tree Pruning" or "Even Tree" to solidify your understanding of tree DP. cut the tree hackerrank solution python

If we cut an edge, the tree splits into two parts. Let's say the smaller part represents a subtree rooted at node $V$. Let $SubtreeSum(V)$ be the sum of the nodes in that subtree. We root at 1 and compute subtree sums:
