Longest Unique Token Span

Easy

Hash TablesArraysStrings

Problem

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

Constraints

0 <= len(s) <= 5 * 10^4
s consists of ASCII letters, digits, symbols, and spaces
A valid solution should run in linear time
