For a undirected graph with tree characteristics, we can choose any node as the root. 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
题目描述 把一个数组最开始的若干个元素搬到数组的末尾,我们称之为数组的旋转.输入一个非递减序列的一个旋转,输出旋转数组的最小元素.例如数组{3,4,5,1,2}为{1,2,3,4,5}的一个旋转,该数组的最小值为1. //这里说的非递减并不是乱序的,也是递增的,只不过递增的过程中可以有相同数字而已 #include <iostream> #include <vector> using namespace std; class Solution { public: int minNu
