题目描述

You are given two positive integers nn ( 1n1091 \le n \le 10^9 ) and kk ( 1k1001 \le k \le 100 ). Represent the number nn as the sum of kk positive integers of the same parity (have the same remainder when divided by 22 ).

In other words, find a1,a2,,aka_1, a_2, \ldots, a_k such that all ai>0a_i>0 , n=a1+a2++akn = a_1 + a_2 + \ldots + a_k and either all aia_i are even or all aia_i are odd at the same time.

If such a representation does not exist, then report it.

输入格式

The first line contains an integer tt ( 1t10001 \le t \le 1000 ) — the number of test cases in the input. Next, tt test cases are given, one per line.

Each test case is two positive integers nn ( 1n1091 \le n \le 10^9 ) and kk ( 1k1001 \le k \le 100 ).

输出格式

For each test case print:

  • YES and the required values aia_i , if the answer exists (if there are several answers, print any of them);
  • NO if the answer does not exist.

The letters in the words YES and NO can be printed in any case.
