Find minimum adjustment cost of an array
Easy Accuracy: 32.57% Submissions: 381 Points: 2

Given an array of positive integers, replace each element in the array such that the difference between adjacent elements in the array is less than or equal to a given target. We need to minimize the adjustment cost, that is the sum of differences between new and old values. We basically need to minimize ∑|A[i] – Anew[i]| where 0 <= i <= n-1, n is size of A[] and Anew[] is the array with adjacent difference less that or equal to target.


The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. The first line of each test case contains two integers N and K where N denotes the size of array A and K is the target.

The second line of each test case contains N space separated integers denoting elements of the array A[ ].


Print the minimum adjustment cost for each test case in a new line.


1<= T <=100

1<= N, K <=1000

1<= A[ ] <=100
