Solution: Longest Subarray With Diff At Most Limit

Explore how to use the sliding window method and two monotonic deques to efficiently solve the longest subarray problem with element differences within a given limit. Understand window expansion and contraction to optimize performance in linear time.

We'll cover the following...

Statement

Given an integer array nums and an integer limit, return the size of the longest non-empty subarray such that the absolute difference between any two elements within that subarray is less than or equal to limit.

Constraints:

  • 1≤1 \leq nums.length ≤105\leq 10^5

  • 1≤1 \leq nums[i] ≤109 ...
