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.
