the reason is min(ti+(ti*T+99)/100,100500*ti) can overflow.
So you are supposed to change long long into unsigned long long,then you'll get AC.

I think that this is too easy problem for 297 points of hardness

This case may help you:
2
A B C
B D Isenbaev

ans:
A 2
B 1
C 2
D 1
Isenbaev 0

Change the statement, don't be ashamed

Try this:
3 3
2 2
3 3

answer: 4

I wish they made clarification

My friends solve it with dicnic.
But its time complexity can be up to O(nm^sqrt(n+m)),and its space compexity can be up to O(nm).
I think admin should add the test that all the bank belong to one country.

I see many people had this WA. Can someone give me a hint about it?
I think it will be useful for others.

The answer is the symmetry axis
In test 3 the angle between the lines is very small

Почему так не проходит(ошибка на 13):
#include <iostream>
int main() {
    int n,k;
    std::cin>>n>>k;
    if(n<=k) std::cout<<2;
    else std::cout<<n*2/k+n*2%k;

return 0;
}

А так проходит:
    #include <iostream>
int main() {
    int n,k;
    std::cin>>n>>k;
    if(n<=k) std::cout<<2;
    else{
        if(n*2 % k == 0) std::cout<<n*2/k;
        else std::cout<<n*2/k+1;
    }
return 0;
}
Ну или тернар(тоже не проходит - ошибка на 13):
#include <iostream>
int main() {
    int n,k;
    std::cin>>n>>k;
    (n<=k)?std::cout<<2:std::cout<<n*2/k+n*2 % k;

return 0;
}
Может я чего не понимаю, может всё-таки где-то приоритет потерял, но ведь идентично же.

Теперь понял, %k может вернуть и больше, чем 1

C++ ответ:
#include <iostream>
int main() {
    int n,k;
    std::cin>>n>>k;
    (n<=k)?std::cout<<2:(n*2%k==0)?std::cout<<n*2/k:std::cout<<n*2/k+1;

return 0;
}

I have some mistake in the staion name which I can't find it in my code.
Then I search all the string my write and calculate LCS.
The string has maximal LCS is what we want to find.
Like that:
int __(string ss){
  if(f.find(ss)==f.end()){
    int ans=0,pos=0;
    rep(ki,1,cnt){
      mst(dp,0);
      for(int i=1;i<=ss.length();i++){
        for(int j=1;j<=s[ki].length();j++){
          if(ss[i-1]==s[ki][j-1])dp[i][j]=dp[i-1][j-1]+1;
          else dp[i][j]=max(dp[i-1][j],dp[i][j-1]);
        }
      }
      if(dp[ss.length()][s[ki].length()]>ans)ans=dp[ss.length()][s[ki].length()],pos=ki;
    }
    return pos;
  }
  return f[ss];
}

Then I got AC from wa2

using System;

namespace _1876_Csharp
{
    class Program
    {
        static void Main(string[] args)
        {
            int a= Convert.ToInt32(Console.ReadLine()), b = Convert.ToInt32(Console.ReadLine());

            int c = Math.Max(2 * a + 39, 2 * b + 40);

            Console.WriteLine(c);
        }
    }
}

There are two variants:
1) You forgot to sort the array
2) You forgot that after sorting the array, indexes are messing up

I've got several times WA 10 and in the forum I couldn't find any test for this test, and finally I found where was the mistake.

Try this:
(*  WTF?!!

)

answer is yes
