This problem is a simple application of Recursion and Depth First Traversal of a tree. You need to solve this problem using post order traversal technique, considering the tree as a rooted tree. Let's take the example given in the question.
The next line contains space-separated integers, each an where each value represents the length of the stick.
Cons. Oct 01, Hackerrank Even Tree Solution. You are given a tree (a simple connected graph with no cycles). Find the maximum number of edges you can remove from the tree to get a forest such that each connected component of the forest contains an even number of nodes. As an example, the following tree with nodes can be cut at most time to create an even shrubhauling.barted Reading Time: 1 min.
Remove an edge from a tree such that the sum of the absolute difference between the value stored at each of the trees' vertices is minimal.
For example, there are sticks of lengths.
