LeetCode 1438. Longest Continuous Subarray With Absolute Diff Less Than or Equal to Limit - TS & JS

Показать описание

The first thought to solve this problem is to use a sliding window approach. The idea is to maintain a window of elements from the array such that the absolute difference between any two elements in this window is less than or equal to the limit. We then try to maximize the size of this window.

Approach
Initialize two deques (double-ended queues), minDeque and maxDeque, to keep track of the minimum and maximum elements in the current window of the array, respectively.
Iterate over the array. For each element, maintain the minDeque and maxDeque.
If the difference between the largest and smallest element in the current window exceeds the limit, slide the window to the right until the condition is satisfied again.
Keep track of the maximum length of the subarray that satisfies the condition.
