题目描述

Connected undirected weighted graph without self-loops and multiple edges is given. Graph contains nn vertices and mm edges.

For each edge (u,v)(u,v) find the minimal possible weight of the spanning tree that contains the edge (u,v)(u,v) .

The weight of the spanning tree is the sum of weights of all edges included in spanning tree.

输入格式

First line contains two integers nn and mm ( 1<=n<=2105,n1<=m<=21051<=n<=2·10^{5},n-1<=m<=2·10^{5} ) — the number of vertices and edges in graph.

Each of the next mm lines contains three integers ui,vi,wiu_{i},v_{i},w_{i} ( 1<=ui,vi<=n,uivi,1<=wi<=1091<=u_{i},v_{i}<=n,u_{i}≠v_{i},1<=w_{i}<=10^{9} ) — the endpoints of the ii -th edge and its weight.

输出格式

Print mm lines. ii -th line should contain the minimal possible weight of the spanning tree that contains ii -th edge.

The edges are numbered from 11 to mm in order of their appearing in input.
