Problem: Longest Substring Without Repeating Characters

Explore how to determine the longest substring without repeated characters by applying the sliding window strategy with hash maps. Understand the implementation details, time and space complexities to efficiently solve this common string algorithm problem in JavaScript.

Statement

Given a string s, determine the length of the longest substring that contains no repeating characters.

A substring is a contiguous sequence of characters within a string.

Note: There may be multiple valid substrings of the same maximum length. Return only the length.

Constraints:

  • 00 \leq s.length 5×104\leq 5 \times 10^4

  • s consists of English letters, digits, symbols, and spaces.
