As to length I expect both languages to end in the same ball park. Here's a
possible Python implementation:
from itertools import zip_longest
def prepare(s):
return map(int, reversed(s.split(",")))
def naive_add(base, left, right):
result = []
carry = 0
for a, b in zip_longest(prepare(left), prepare(right), fillvalue=0):
carry, rest = divmod(a + b + carry, base)
result.append(rest)
if carry:
result.append(carry)
return ",".join(map(str, reversed(result)))
if __name__ == "__main__":
print(naive_add(16, "1,2", "13,14"))
The Python code for sure has better indentation ;)
