Problem: You are given a weighted undirected connected graph consisting of n vertices and m edges. It is guaranteed that there are no self-loops or multiple edges in the given graph.

Let's define the weight of the path consisting of k edges with indices e_1, e_2, ..., e_k as ∑_{i=1}^{k}{w_{e_i}} - max_{i=1}^{k}{w_{e_i}} + min_{i=1}^{k}{w_{e_i}}, where w_i — weight of the i-th edge in the graph.

Your task is to find the minimum weight of the path from the 1-st vertex to the i-th vertex for each i (2 ≤ i ≤ n).

Input

The first line contains two integers n and m (2 ≤ n ≤ 2 ⋅ 10^5; 1 ≤ m ≤ 2 ⋅ 10^5) — the number of vertices and the number of edges in the graph.

Following m lines contains three integers v_i, u_i, w_i (1 ≤ v_i, u_i ≤ n; 1 ≤ w_i ≤ 10^9; v_i ≠ u_i) — endpoints of the i-th edge and its weight respectively.

Output

Print n-1 integers — the minimum weight of the path from 1-st vertex to the i-th vertex for each i (2 ≤ i ≤ n).
