The slight error with your code is that you have initialized diff to 0. So if a’s and b’s which you will get are equal then a-b or b-a will never be greater than diff hence your x value will never update. So it will give you a wrong answer. I submitted your code which gave the correct answer :

still getting wrong answer

Dont know why are you doing p=p+a; and q=q+b; as the scores of each round are calculated separated according to new rules(as in question)... You can simply use p=a and q=b and there is no problem whatsoever if you dont use p and q…as a-b or b-a have no use further in next upcoming rounds

I have edited the answer above. Check for your errors.
