Picking Numbers

Given an array of integers, find the longest subarray where the absolute difference between any two elements is less than or equal to .

Example

There are two subarrays meeting the criterion: and . The maximum length subarray has elements.

Function Description

Complete the pickingNumbers function in the editor below.

pickingNumbers has the following parameter(s):

  • int a[n]: an array of integers

Returns

  • int: the length of the longest subarray that meets the criterion

4 6 5 3 3 1

Sample Output 0

3

Explanation 0

We choose the following multiset of integers from the array: . Each pair in the multiset has an absolute difference (i.e., and ), so we print the number of chosen integers, , as our answer.
