why wrong answer for the lead game?

t = int(input())

list1,list2 = [],[]

for i in range(0,t):

c,d = map(int,input().split())

list1.append(c)
list2.append(d)

l,w,win = 0,0,0

for i in range(t):

w = abs(list1[i]-list2[i])

if w>l:
    l = w

    if list1[i]>list2[i]:
        win = 1

    else :
        win = 2

print(win,l)

//
