Longest Unique Substring Window

Easy

RecursionHash TablesArrays

Problem

Given a string s, return the length of the longest substring that contains no repeated characters. A substring must be contiguous. The input is a string, and the output is a single integer.

Constraints

0 <= len(s) <= 5 * 10^4
s consists of English letters, digits, symbols, and spaces
An O(n) solution is expected
