I am doing BENEFACT — The Benefactor.

I am using 2-time BFS method to calculate the longest path. Because here cost is associated with every edge so I am doing 2 times Dijkstra instead of 2 times BFS. But I am getting WA.

Can Anyone tell me Why I am getting WA?

Here is my code.

Edit:- Now I have done uknowg BFS instead of Dijkstra and I got Ac. Here is my code.

I want to now why solution using Dijkstra give WA and BFS gives AC.

Can Anyone help me? Please

Dont think dijkstra's will work here. You can check my implementation if that helps.submission
