Description

Input

The input consists of multiple test cases. The first line contains an integer $t$ ($1 \leq t \leq 100$) — the number of test cases. The description of the test cases follows.

The only line of each test case contains two integers $s$ and $n$ ($1 \leq s \leq 10^9$; $1 \leq n \leq \min(100, s)$) — the sum and amount of numbers on the board, respectively. Numbers $s$ and $n$ are given in decimal notation (base $10$).

Output

For each test case, output $n$ positive integers — the numbers Bob should write on the board, so Alice's sum is as large as possible. If there are multiple answers, print any of them.

Note

In the first test case, $70_{10} + 27_{10} = 97_{10}$, and Alice's sum is $$70_{11} + 27_{11} = 97_{11} = 9 \cdot 11 + 7 = 106_{10}.$$ (Here $x_b$ represents the number $x$ in base $b$.) It can be shown that it is impossible for Alice to get a larger sum than $106_{10}$.

In the second test case, Bob can only write a single number on the board, so he must write $17$.

In the third test case, $3_{10} + 4_{10} + 100_{10} + 4_{10} = 111_{10}$, and Alice's sum is $$3_{11} + 4_{11} + 100_{11} + 4_{11} = 110_{11} = 1 \cdot 11^2 + 1 \cdot 11 = 132_{10}.$$ It can be shown that it is impossible for Alice to get a larger sum than $132_{10}$.
