1438. Longest Continuous Subarray With Absolute Diff Less Than or Equal to Limit

https://leetcode.com/problems/longest-continuous-subarray-with-absolute-diff-less-than-or-equal-to-limit

Description

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

Example 1:

**Input:** nums = [8,2,4,7], limit = 4
**Output:** 2 
**Explanation:** All subarrays are: 
[8] with maximum absolute diff |8-8| = 0 <= 4.
[8,2] with maximum absolute diff |8-2| = 6 > 4. 
[8,2,4] with maximum absolute diff |8-2| = 6 > 4.
[8,2,4,7] with maximum absolute diff |8-2| = 6 > 4.
[2] with maximum absolute diff |2-2| = 0 <= 4.
[2,4] with maximum absolute diff |2-4| = 2 <= 4.
[2,4,7] with maximum absolute diff |2-7| = 5 > 4.
[4] with maximum absolute diff |4-4| = 0 <= 4.
[4,7] with maximum absolute diff |4-7| = 3 <= 4.
[7] with maximum absolute diff |7-7| = 0 <= 4. 
Therefore, the size of the longest subarray is 2.

Example 2:

**Input:** nums = [10,1,2,4,7,2], limit = 5
**Output:** 4 
**Explanation:** The subarray [2,4,7,2] is the longest since the maximum absolute diff is |2-7| = 5 <= 5.

Example 3:

**Input:** nums = [4,2,2,2,4,4,2,2], limit = 0
**Output:** 3

Constraints:

• 1 <= nums.length <= 105

• 1 <= nums[i] <= 109

• 0 <= limit <= 109
