Longest Substring Without Repeating Characters
Detailed guide and Python implementation for the 'Longest Substring Without Repeating Characters' problem.
Problem Statement
Given a string s, find the length of the longest substring without repeating characters.
Write a function lengthOfLongestSubstring(s: str) -> int.
- •0 <= len(s) <= 5 * 10^4
- •s consists of English letters, digits, symbols, and spaces
Examples
s = "abcabcbb"
3
The answer is "abc", with a length of 3.
s = "bbbbb"
1
The answer is "b", with a length of 1.
s = "pwwkew"
3
The answer is "wke", with a length of 3. Note that "pwke" is a subsequence, not a substring.
