if(a[l]+a[r]==sum)
cout<<a[l]<<" and "<<a[r]<<endl;
else if(a[l]+a[r]<sum)
l++;
else
r–;

Hi @agarwalarjit.agarwal
in dis case
if(a[l]+a[r]==sum)
cout<<a[l]<<" and "<<a[r]<<endl;

add l++;r–; since once u have found the sum, u move both the pointer to the next position.
Hope dis helps.
If something is still unclear, feel free to post ur doubt here

it is solved, thanks for the assistance
