Problem: Longest Substring Without Repeating Characters

Understand how to determine the length of the longest substring without repeating characters by applying the sliding window technique combined with hash maps. Learn to efficiently track characters and adjust pointers to solve this problem with linear time complexity. This lesson helps build foundational skills in string manipulation and algorithmic optimization in Go.

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.
