Hello,

I need help with the TLG Practice Problem.
Seems pretty simple, but when I submit the code I always get back the “Wrong Answer” error.
This is my code:

#include <iostream>
using namespace std;
int main() {
   int N;
   int L = 0; // this is the lead
   int W;   // this indicates the winner
   scanf("%d", &N);
   while (N--) {
       int Si, Ti;
       scanf("%d %d", &Si, &Ti); //scanning scores
       int diff; // difference between scores
       if (Si > Ti) {
           diff = Si - Ti;
           if(diff > L) {
               L = diff;
               W = 1;
           }
       } else {
           diff = Ti - Si;
           if(diff > L) {
               L = diff;
               W = 2;
           }
       }
   }
   printf("%d %d\n", W, L);
	return 0;
}

Thank you in advance for your help!
