The lead game : what is wrong with my code?

The code chef compiler is giving wrong answer to this code…but is working fine on my PC :confused:

#include<stdio.h>
int main()
{
	int r,i,min=0,max=0,a[10000],b[10000],c[10000];
	scanf("%d",&r);
	for(i=0;i<r;i++)
	{
		scanf("%d%d",&a[i],&b[i]);
		c[i]=a[i]-b[i];
		if(c[i]<min)
            min=c[i];
        if(c[i]>max)
            max=c[i];
 
	}
	if(min*-1>max)
        printf("2 %d",min*-1);
    else
        printf("1 %d",max);
 
	return 0;
 
}
2

if both min*-1 and max are equal what should be the output

@swati4star For the given testcase, your code may work…but it is not correct.

here you are storing the lead values of each round in the array c[10000].

Those lead values are actually not a[i]-b[i]…it is actually

the sum of the scores of the player1 upto the "i"th round - the sum of the scores of the player2 till "i"th round…

so take care of that c[10000]…then your code may give AC for codechef compiler also :slight_smile:

If this helps…hope you can upvote and accept the answer…

All the Best :slight_smile:

It is given in the question that…

" You may assume that the scores will be such that there will
always be a single winner. That is, there are no ties."
