Hell, man. Thanks :) I will read now very carefully.

I just passed that question and making others now, but anyway cannot understand why this code is not working well

Hi there, Thank you for reply, here is my code

n = int(input())
 
max = 0
w, l = 0, 0
 
for i in range(n):
    p1, p2 = map(int, input().split())
    if p1 > p2:
        if max < p1 - p2:
            max = p1 - p2
            w = 1
            l = max
    else:
        if max < p2 - p1:
            max = p2 - p1
            w = 2
            l = max
 
print (w, l) 

Hi guys, I am not so exprienced in this kinda things. What kinda inputs there should be? I wrote my program it is working well in my local, but the server shows it is wrong. I am writing in python and taking input with raw_input() and just printing output
