Given a binary tree, find the maximum path sum. For this problem, a path is defined as any sequence of nodes from some starting node to any node in the tree along the parent-child connections. The path does not need to go through the root. For example: Given the below binary tree, ...
To find which subtree it lies in, we can use binary lifting to find the node just below the top vertex in the path. since the adding edges part is O(k)O(k), my time complexity is now O(n+Qklogn)O(n+Qklogn). I would think there exists a better solution however. → Reply...
