, b
):
s
= ''.join
(
str((x
+ y
) % 10)
for x
, y
in zip_longest
(map(int, str(a
)[::-1]), map(int, str(b

return s
答案7:

答案8:
def addition_without_carrying(a

(6)
return int(''.join

in range(6)]))
答案9:
from itertools

):
args
= [map(int, str(i
)[::-1]) for i
in args
]
return int(''.join
(str(sum(i
)%10) for i
in zip_longest

=0))[::-1])
答案10:
def addition_without_carrying(a

= str(b
)[::-1]
maxLen
= max(len(a

answer
= []
for i
in range(0, maxLen
):
answer
.append
