Describe an advanced data structure : Binary Searching for an Optimal Subarray Length

The video tutorial explains how to find the longest subarray where the difference between the maximum and minimum values is less than or equal to a given number K. It introduces the use of binary search to determine the optimal subarray length and explains the logic behind why binary search is applicable. The tutorial provides a step-by-step guide to implementing the binary search algorithm, including setting up tests to verify its correctness. Additionally, it hints at an alternative solution using decks and encourages viewers to explore this method.
