题目描述

On the board, Bob wrote nn positive integers in base 1010 with sum ss (i. e. in decimal numeral system). Alice sees the board, but accidentally interprets the numbers on the board as base- 1111 integers and adds them up (in base 1111 ).

What numbers should Bob write on the board, so Alice's sum is as large as possible?

输入格式

The input consists of multiple test cases. The first line contains an integer tt ( 1t1001 \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 ss and nn ( 1s1091 \leq s \leq 10^9 ; 1nmin(100,s)1 \leq n \leq \min(100, s) ) — the sum and amount of numbers on the board, respectively. Numbers ss and nn are given in decimal notation (base 1010 ).

输出格式

For each test case, output nn 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.

说明/提示

In the first test case, 7010+2710=971070_{10} + 27_{10} = 97_{10} , and Alice's sum is $$$$70_{11} + 27_{11} = 97_{11} = 9 \cdot 11 + 7 = 106_{10}. $$ (Here x_bx\_b represents the number xx in base bb .) It can be shown that it is impossible for Alice to get a larger sum than 106_10106\_{10} .

In the second test case, Bob can only write a single number on the board, so he must write 1717 .

In the third test case, 3_10+4_10+100_10+4_10=111_103\_{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_10132\_{10}$$.
