Problem

Tech(x) Preview displays a continuous segment of user-visible text in its compact interface. Given a string s, return the length of the longest substring containing no repeated characters.

A substring must use consecutive characters from s. Characters are case-sensitive, so A and a are different.

Formal Specification

Implement length_of_longest_substring(s), where s is a string. Return an integer representing the maximum length of any substring with all unique characters.

Constraints

0 <= len(s) <= 5 * 10^4
s contains printable ASCII characters
Characters are case-sensitive
Return 0 for an empty string

Function Signature

def length_of_longest_substring(s):
