can you please fix the AssertionError in this: (please don't use try and except or break/continue or recursion)

def long_new(s: str) -> str:

longest_string = 0
longest_substring = s[0]
i = 0
inputs = {s[i]: i}
j = i + 1
while j < len(s):
while j < len(s) and (inputs.get(s[j], -1) == -1):
inputs[s[j]] = j
j = j + 1
if j - 1 > longest_string:
longest_string = j - i
longest_substring = s[i:j]
if j >= len(s):
return longest_substring
i = inputs[s[j]] + 1
inputs = {}
j = i + 1
if j - i > longest_string:
longest_string = j - i
longest_substring = s[i:j]
return longest_substring

print(long_new(aab))

The print statement should print 'ab'
