Показать описание
Longest Substring Without Repeating Characters SOLUTION (Leetcode #3). Here is a step by step explanation of the algorithm problem on the LeetCode platform. The time and space complexity of our sliding window solution is O(N) where N is the number of characters we have in our input string. This problem is asked at many tech companies including Google, Facebook, Amazon, Uber, Adobe, and many more. In this tutorial video, I go over the sliding window technique. A sliding window algorithm will form a window, or section, around parts of the data. Incrementally, this window will move over the data and perform some sort of computation.
