DESCRIPTION

      Eric has an array of integers 
a1,a2,...,ana1,a2,...,an. Every time, he can choose a contiguous subsequence of length 
kk and increase every integer in the contiguous subsequence by 
11.He wants the minimum value of the array is at least 
mm. Help him find the minimum number of operations needed. 

INPUT

      There are multiple test cases. The first line of input contains an integer 
TT, indicating the number of test cases. For each test case:The first line contains three integers 
nn, 
mm and 
kk
(1≤n≤105,1≤k≤n,1≤m≤104)(1≤n≤105,1≤k≤n,1≤m≤104).The second line contains 
nn integers 
a1,a2,...,ana1,a2,...,an
(1≤ai≤104)(1≤ai≤104). 

OUTPUT

      For each test case, output an integer denoting the minimum number of operations needed.
