What's wrong with my code : The Lead Game - TLG (Beginner level)

#include
using namespace std;
int main()
{
ios_base::sync_with_stdio(false);
cin.tie(NULL);
int n;
cin>>n;
int a,b;
int dif[2]={0};
for(int i=0;i<n;i++)
{
cin>>a>>b;
if(a>b && (a-b)>dif[1])
{
dif[1]=a-b;
dif[0]=1;
}
else if(b-a>dif[1])
{
dif[1]=b-a;
dif[0]=2;
}
}
cout<<dif[0]<<" "<<dif[1]<<endl;
}

Cumulative lead, not lead per round.

As mentioned by @vijju123, you would need to calculate the cumulative lead after each round and then check for the diff. Currently, with (a-b)>dif[1] and b-a>dif[1], you are checking for lead in each round.

Try accumulating a’s and b’s individually, say in ‘x’ and ‘y’, and then check for difference of x and y instead of directly checking for the difference of ‘a’ and ‘b’.

Thankyou, I’d missed the “cumulative” in there. Thanks a lot.
