( 3799 ) E Minimum Path PROGRAMMING dp graphs implementation shortest paths

B"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 sum limits_{i=1}^{k}{w_{e_i}} - max limits_{i=1}^{k}{w_{e_i}} + min limits_{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 ). The first line contains two integers n and m ( 2 <= n <= 2 cdot 10^5 ; 1 <= m <= 2 cdot 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 neq u_i ) -- endpoints of the i -th edge and its weight respectively. 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 ). "...
