Leetcode minimize the height

Nettet27. mar. 2024 · When you select a node x as the root, the result tree has height h. Among all possible rooted trees, those with minimum height (i.e. min(h)) are called minimum height trees (MHTs). Return a list of all MHTs’ root labels. You can return the answer in … NettetExplanation: we get the minimum height as 2 when node 3 and 4 are selected as roots & hence the answer is [3,4] Approach The most obvious intuition that comes to mind is to apply the shortest path algorithm to find the distance between the root node to all other nodes. This approach requires applying Dijkstra from all nodes.
