what is wrong here?
lead = lead + p1-p2
This seems wrong to me since lead in one round is independent of other/previous rounds. MEaning, if 1 had lead of 50 in round one, and next round scores are Player1- 250, player2 -260 then elad of 2 will be 10. But your statement will do lead = 50(lead) -10 (p1-p2)
Greetings!
May I ask for an optimal test case for this problem?
all the test cases that I use are confirmed but I am still getting wrong answer on submission
and I need to check if I am doing wrong and where.
Best Regards.
Robert.
Here is my code:

Hi, the problem with your code is that it only gives the output result of the last scores input in it. You need to give the result from all of the rounds’ scores input.
import java.util.*;
class {
public static void main(String[] args)
{
Scanner sc=new Scanner(System.in);
int t=sc.nextInt();
int p11[]=new int[t];
int p22[]=new int[t];
if(t<=10000)
{
for(int i=0;i<t;i++)
{
int p1=sc.nextInt();
int p2=sc.nextInt();
p11[i]=(p1-p2);
p22[i]=(p2-p1);
}}
Arrays.sort(p11);
Arrays.sort(p22);
if(p11[t-1]>p22[t-1])
{
int k=1;
System.out.print(k+" "+p11[t-1]);
}
else{
int l=2;
System.out.print(l+" "+p22[t-1]);}
}
}
This is my code. its working fine with the sample test but is giving it wrong answer.
no use of array is required

winner=(si>ti)?(1):(2);
lead=abs(si-ti);
v.push_back(make_pair(lead,winner));
}
sort(v.begin(),v.end(),greater< pair<int,int> >());
cout<<v[0].second<<" "<<v[0].first<<endl;
v.clear();
return 0;

Code Works fine. why codechef showing Wrong Answer??

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?

What’s gone wrong with this code?? Runs perfectly in codeshef’s practice IDE but on question’s IDE show wrong answer.
