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

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

Leetcode Solutions

Initialize two empty dequeues: minDeque for tracking the minimum values and maxDeque for tracking the maximum values.
Initialize two pointers left and right to 0, which represent the bounds of the current window.
Iterate over the array using the right pointer.
- While adding a new element to the window, remove elements from the back of both deques that are not valid candidates for the new window maximum or minimum.
- Add the current element's index to the back of both deques.
If the difference between the maximum and minimum elements in the window exceeds the limit, increment the left pointer to shrink the window from the front, and remove the front elements of the deques if they are equal to nums[left].
Update the result with the maximum window size seen so far.
Return the result after the iteration is complete.
