Help me debugging TLG

why am I getting the wrong answer although my output is correct?! here's the Q:https://www.codechef.com/problems/TLG my code(c):

#include <stdio.h>
#include <stdlib.h>
int r;
int main()
{


    scanf("%d",&r);
    int sc[r][4],i,max1=0,max2=0;
    for(i=0;i<r;i++)
    {


        scanf("%d",&sc[i][0]);scanf("%d",&sc[i][1]);
        if(sc[i][0]>sc[i][1])
        {
        sc[i][2]=(sc[i][0]-sc[i][1]);
        sc[i][3]=0;}
        else
            {
            sc[i][3]=(sc[i][1]-sc[i][0]);
            sc[i][2]=0;}


    }
     max1=sc[0][2];
     max2=sc[0][3];
    for (i=0;i<r;i++)
    {

        if(sc[i][2]>max1)
           {
              max1=sc[i][2];
           }
         if(sc[i][3]>max2)
           {
              max2=sc[i][3];
           }
    }
    if(max1>max2)
        {printf("\n%d",1);printf(" %d",max1);}
    else
        {printf("\n%d",2);printf(" %d",max2);}

    return 0;
}
