题目描述
You are given two positive integers n ( 1≤n≤109 ) and k ( 1≤k≤100 ). Represent the number n as the sum of k positive integers of the same parity (have the same remainder when divided by 2 ).
In other words, find a1,a2,…,ak such that all ai>0 , n=a1+a2+…+ak and either all ai are even or all ai 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 t ( 1≤t≤1000 ) — the number of test cases in the input. Next, t test cases are given, one per line.
Each test case is two positive integers n ( 1≤n≤109 ) and k ( 1≤k≤100 ).
输出格式
For each test case print:
- YES and the required values ai , 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.
