🔥 FULLTIME

Given an Array A, find the minimum amplitude you can get after changing up to 3 elements. Amplitude is the range of the array (basically difference between largest and smallest element).

Example 1: 

Input:  A = [-1, 3, -1, 8, 5, 4]
Output: 2 
Explanation:

We can change -1, -1, 8 to 3, 4 or 5.

Example 2: 

Input:  A = [10, 10, 3, 4, 10]
Output: 0
