详细说明： Problem Description There is an undirected graph G with n vertices and m edges. Every time, you can select several edges and delete them. The edges selected must meet the following condition: let G′ be graph induced from these edges, then every connected component of G′ has at most one cycle. What is the minimum number of deletion n eeded in order to delete all the edges. Input There are multiple test cases. The first line of input contains an integer T indicating the number of test cases. For each test case: The first line contains two integers n and m (1≤n≤2000,0≤m≤2000) -- the number of vertices and the number of edges. For the next m lines, each line contains two integers ui and vi, which means there is an undirected edge between ui and vi (1≤ui,vi≤n,ui≠vi). The sum of values of n in all test cases doesnt exceed 2⋅104. The sum of values of m in all test cases doesnt exceed 2⋅104. Output For each test case, output the minimum number of deletion needed.
