The height of a rooted tree is the number of edges on the longest downward path between the root and a leaf. 描述 对于一个具有树特征的无向图,我们可选择任何一个节点作为根。图因此可以成为树,在所有可能的树中,具有最小高度的树被称为最小高度树。给出这样的一个图,写出一个函数找到所有的最小...
The result graph is then a rooted tree. Among all possible rooted trees, those with minimum height are called minimum height trees (MHTs). Given such a graph, write a function to find all the MHTs and return a list of their root labels. FormatThe graph contains n nodes which are ...
