For the first time, Polycarp's startup ended the year with a profit! Now he is about to distribute $$$k$$$ burles as a bonus among $$$n$$$ employees.

It is known that the current salary of the $$$i$$$-th employee is $$$a_i$$$ and all the values of $$$a_i$$$ in the company are different.

Polycarp wants to distribute the $$$k$$$ burles between $$$n$$$ employees so this month the $$$i$$$-th employee will be paid not $$$a_i$$$, but $$$a_i+d_i$$$ ($$$d_i \ge 0$$$, $$$d_i$$$ is an integer), where $$$d_i$$$ is the bonus for the $$$i$$$-th employee. Of course, $$$d_1+d_2+\dots+d_n=k$$$.

Polycarp will follow two rules for choosing the values $$$d_i$$$:

  • the relative order of the salaries should not be changed: the employee with originally the highest salary ($$$a_i$$$ is the maximum) should have the highest total payment after receiving their bonus ($$$a_i+d_i$$$ is also the maximum), the employee whose salary was originally the second-largest should receive the second-largest total payment after receiving their bonus and so on.
  • to emphasize that annual profit is a group effort, Polycarp wants to minimize the maximum total payment to an employee (i.e minimize the maximum value of $$$a_i+d_i$$$).

Help Polycarp decide the non-negative integer bonuses $$$d_i$$$ such that:

  • their sum is $$$k$$$,
  • for each employee, the number of those who receive strictly more than them remains unchanged (that is, if you sort employees by $$$a_i$$$ and by $$$a_i+d_i$$$, you get the same order of employees),
  • all $$$a_i + d_i$$$ are different,
  • the maximum of the values $$$a_i+d_i$$$ is the minimum possible.

Help Polycarp and print any of the possible answers $$$d_1, d_2, \dots, d_n$$$.


The first line contains an integer $$$t$$$ ($$$1 \le t \le 10^4$$$) — the number of test cases in the input. Then $$$t$$$ test cases follow.

The first line of each test case contains two integers $$$n$$$ and $$$k$$$ ($$$1 \le n \le 10^5$$$, $$$1 \le k \le 10^9$$$) — the number of employees and the total bonus.

The second line of each test case contains $$$n$$$ different integers $$$a_1, a_2, \dots, a_n$$$ ($$$1 \le a_i \le 10^9$$$), where $$$a_i$$$ is the current salary of the $$$i$$$-th employee.

It is guaranteed that the sum of all $$$n$$$ values in the input does not exceed $$$10^5$$$.


Print the answers to $$$t$$$ test cases in the order they appear in the input. Print each answer as a sequence of non-negative integers $$$d_1, d_2, \dots, d_n$$$. If there are several answers, print any of them.
