MediumPython

Problem

Solve a problem where you need to find the longest substring without repeating characters.

Implement def length_of_longest_substring(s):, which accepts a string and returns the length of its longest contiguous substring containing no repeated characters. Aim for an O(n) solution using a sliding window.

Constraints

0 <= len(s) <= 50000
s contains printable ASCII characters
The substring must be contiguous
Return only the maximum length, not the substring itself

Function Signature

def length_of_longest_substring(s):
