题目描述
Little Q’s factory recently purchased m pieces of new equipment, labeled by 1, 2, . . . , m.
There are n workers in the factory, labeled by 1, 2, . . . , n. Each worker can be assigned to no more than
one piece of equipment, and no piece of equipment can be assigned to multiple workers. If Little Q assigns
the i-th worker to the j-th piece of equipment, he will need to pay ai × j2 + bi × j + ci dollars.
Now please for every k (1 ≤ k ≤ n) fifind k pairs of workers and pieces of equipment, then assign workers
to these pieces of equipment, such that the total cost for these k workers is minimized.
输入格式
The first line of the input contains a single integer T(1≤T≤10
), the number of test cases.

(1≤n≤50
, n≤m≤10
8
), denoting the number of workers and the number of pieces of equipment.
输出格式
For each test case, output a single line containing n integers, the k-th (1 ≤ k ≤ n) of which denoting the
minimum possible total cost for k pairs of workers and pieces of equipment.
