Longest Contiguous Subarray With Absolute Diff Bounded by a Limit

Difficulty: Easy


Try Problem

Given an array/list 'ARR' of integers and an integer 'LIMIT'. You are supposed to return the length of the longest subarray for which the absolute difference between the maximum and minimum element is less than or equal to the 'LIMIT'.

Note :
An array ‘B’ is a subarray of an array ‘A’ if ‘B’ that can be obtained by deletion of, several elements(possibly none) from the start of ‘A’ and several elements(possibly none) from the end of ‘A’. 
Input Format :
The first line contains a single integer ‘T’ denoting the number of test cases. Then the 'T'  test cases follow.

The first line of each test case contains two integers separated by single space ‘N’ and 'LIMIT' denoting the number of elements in the array/list.

The second line of each test case contains ‘N’ single space-separated integers denoting the elements of the array/list.
Output Format :
For each test case, print a single line that contains an integer that denotes the length of the longest contiguous subarray with absolute difference bounded by the 'LIMIT'.
Note :
You do not need to print anything, it has already been taken care of. Just implement the given function.
Constraints :
1 <= 'T' <= 50
1 <= 'N' <= 10^4
0 <= 'ARR[i]' <= 10^5
0 <= 'LIMIT' <= 10^5

Where 'ARR[i]' denotes the ith elements of the given array/list.
