I am working on the problem of finding the minimum path sum in a binary tree, and printing the path. Let us write c program and learn how it works. Sign up for free to join this conversation on GitHub. Condition (2) tries to keep the tree fairly bushy by insisting that each node have at least half the maximum number of children. Path Sum II. Using a tree (actually a binary trie, more on that later) all characters are stored at the leaves of a complete tree. Means in all the paths from root to leaves, find the path which has the maximum sum.
