What is wrong with this code for TLG problem?

,

The link to problem : TLG

My code :

/* PROB - TLG */
 
#include <stdio.h>
 
int main(void) {
	// your code goes here
	int t,win=1,diff=-1,lead=0,s1,s2;
	scanf("%d\n", &t);
	while(t--)
	{
	    scanf("%d\n", &s1);
	    scanf("%d\n", &s2);
	    if(diff==-1)
	    {
	        if(s1>s2)
	        {
	            lead = diff = s1-s2;
	            win = 1;
	        }
	        else
	        {
	            lead = diff = s2-s1;
	            win = 2;
	        }
	    }
	    else
	    {
	        if(s1>s2)
	        {
	            diff = s1-s2;
	            if(diff>lead)
	            {
	                lead=diff;
	                win = 1;
	            }
	        }
	        else
	        {
	            diff = s2-s1;
	            if(diff>lead)
	            {
	                win = 2;
	                lead = diff;
	            }
	        }
	    }
	}
	printf("%d %d\n", win, lead);
	return 0;
}

The scores of previous round accumulate!!

Meaning, Take this example-

2
140 82
89 155

In first case, player 1 leads by 58 points. In second round, ALTHOUGH player 2 achieves a lead of 66, we have to see the accumulated scores. So lead for round 2 is (82+155)-(140+89)=8 .

I got AC when i followed this logic. Refer to the table given in problem statement for more details.

Your code finds the difference for each round individually but the question requires you to find the difference between the cumulative scores till that round.

Even i got stuck on that part while solving it XD. A good lesson on reading problem statement minutely haha.

Got that. I think i might’ve just skimmed past that table. :stuck_out_tongue_winking_eye:
