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 (1n105,1kn,1m104)(1≤n≤105,1≤k≤n,1≤m≤104). The second line contains nn integers a1,a2,...,ana1,a2,...,an (1ai104)(1≤ai≤104).
OUTPUT For each test case, output an integer denoting the minimum number of operations needed. SAMPLE INPUT 3 2 2 2 1 1 5 1 4 1 2 3 4 5 4 10 3 1 2 3 4 SAMPLE OUTPUT 1 0 15 SOLUTION “玲瓏杯”ACM比賽 Round #1 【題意】:給你一個長度為n的序列,每次你只能選擇連續的k個數字加1,問你要進行多少次操作才能使所有的a[i]都大於m。 【分析】: 【代碼】:
