WA
Hi, I'm new to min cost flow problems and I'm getting WA. The approach I follow is this: 1. Find the augumenting path which has the shortest path (Dijkstra) . Then, I remove the used edge u-v. (However, the edge v-u remains). 2. Continue till I get the desired flow. This works on all the test cases ...

Why WA??
This is one of the worst problems of this archive. What is it that they are trying to test, our problem solving ability, or our ability to parse the input? Anyway, I keep getting WA after repeated submissions. Could anyone point out the mistake in the code, or provide me with sample I/O with which I...

Why WA??
Perhaps the last solution is a bit slow. But I see no reason why it shouldnt be correct. Anyway, here's the new solution. Please Please give me test cases where my program fails or point out the mistake in my code. Here goes: #include<iostream> #include<cstdio> #include<vector> #include<string> #inc...

WHY WA??
Hi, I'm trying to solve 11072 and am getting WA. My idea: Compute the convex hull. Then, to check if the points lie inside the hull, check if the absolute value of the sum of areas formed by the triangle and 2 points of the hull is equal to the area of the convex hull. Is this correct? I think so, b...

Some clarifications needed
Hi, I have 2 doubts: 1. Can the guy visit a spot he has already visited? 2. When he walks without any treasures, he takes energy required in calories for a walk from a block to an adjacent one * distance. When carrying treasures, is this cost added? 3. If a guy passes through a point which contains ...
