Snuke has a grid consisting of three squares numbered 1, 2 and 3. In each square, either `0` or `1` is written. The number written in Square i is s_i.  Snuke will place a marble on each square that says `1`. Find the number of squares on which Snuke will place a marble.
s = input()
ans = 0
for i in range(3):
  if s[i] == 1:
    ans += 1
print(ans)
s = list(input())
ans = 0
for i in range(3):
  if s[i] == '1':
    ans += 1
print(ans)
