    Break the problem into two parts :

    1. Assume you have no data about the current city. Get the minimum distance b/w any two chocolate cities. You need to calculate this distance for each chocolate city.(Think about this how you can achieve it..?)

    2. Next step, get the distance b/w current city and each chocolate city. As you already know the minimum distance b/w two chocolate cities for each city. You can get the final answer easily :)

killjee

The problem Can Killjee win some chocolates have wrong test cases. Your solution contains a line :

typedef int ll;

which is causing overflow and negative values are being printed.

We solved the problem correctly and were repeatedly getting WA verdict during the contest. After the contest when we changed ll to int the solution was accepted. We checked the test files, the correct output file contains negative numbers which is not possible as per the question.

Please rejudge all the submissions for this problem and for the problem Killjee wants to sort chocolates. Many teams suffered a lot because of these mistakes. This is not at all good.
