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.
Why is this wrong??

i am getting wa(wrong answer)
whats wrong in my code
import java.util.Scanner;
public class TheLeadGame
{
public static void main(String[] Sym)
{
Scanner sym = new Scanner(System.in);
int round = sym.nextInt();
int[] intarrr = new int[]{0,0};
for (int i = 0; i < round; i++)
{
int a = sym.nextInt();
int b = sym.nextInt();
int absVal = Math.abs(a-b);
if(intarrr[1] < absVal)
{
intarrr[1] = absVal ;
intarrr[0] = (a > b) ? 1 : 2;
}
}
System.out.println(intarrr[0] + " " + intarrr[1]);
sym.close();
}
}
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.
I did that without using any array. what is problem with my code.
#include <iostream>
using namespace std;
int main()
{
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;
}what is wrong with my code. whenever i am submitting it , its showing wrong answer , but i have tried many test cases and all working fine . please reply . thanku…
