Once all the rounds are over the player who had the maximum lead at the end of any round in the game is declared the winner.
I think it means any game out of all having highest lead decide the winner right ?
but that is not the case being accepted here.
if other player catches up the lead in 2 or 3 games like Highest lead is say 50 and other person manages lead of 30 in 2 games, he/she is winner.
This is so confusing.
What is the problem with my code?

I don’t think there is need of creating 4 arrays. I solved this answer using 4 variables only. Codechef shows wrong answer when I submit my code but when I run the code on my computer the answer that I get always correct. Below is the code that I wrote.
#include <iostream>
using namespace std;
int main()
{
short int t,p1,p2,m1=0,m2=0;
cin >> t;
while(t--)
{
cin >> p1 >> p2;
if(p1>p2 && (p1-p2)>m1)
m1 = p1-p2;
else if(p2>p1 && (p2-p1)>m2)
m2 = p2-p1;
}
if(m1>m2)
cout << 1 << " "<<m1<<endl;
else
cout << 2 << " "<<m2<<endl;
return 0;
}using namespace std;
int main()
{
int R;
cin>>R;
int P1[R],P2[R],maximum=0,diff=0,W=0;
for(int a=0;a<R;a++)
{
cin>>P1[a]>>P2[a];
if(P1[a]>P2[a])
{
diff=P1[a]-P2[a];
if(diff>maximum)
{
W=1;maximum=diff;
}}
else{diff=P2[a]-P1[a]; if(diff>maximum){W=2;maximum=diff;}
}
}
cout<<W<<" "<<maximum<<endl;
return 0;
}
what is wrong with this code. The answer matched with several test data.
