The Lead Game - What is wrong with my code?

I tried to find the mistake in my code, but i couldn’t. It seems (to me) to be right.

t = int(input())
w = []
d = []
for i in range (t):
  a,b = map(int, input().split())
  if a > b:
    w += [1]
  else:
    w += [2]
  d += [abs(a-b)]
print (str(w[d.index(max(d))]), str(max(d)))
