2914:Minimum Cut

题目描述

Given an undirected graph, in which two vertices can be connected by multiple edges, what is the size of the minimum cut of the graph? i.e. how many edges must be removed at least to disconnect the graph into two subgraphs?

输入解释

Input contains multiple test cases. Each test case starts with two integers N and M (2 ≤ N ≤ 500, 0 ≤ MN × (N − 1) ⁄ 2) in one line, where N is the number of vertices. Following are M lines, each line contains M integers A, B and C (0 ≤ A, B < N, AB, C > 0), meaning that there C edges connecting vertices A and B.

输出解释

There is only one line for each test case, which contains the size of the minimum cut of the graph. If the graph is disconnected, print 0.
