You have been blessed as a child of Omkar. To express your gratitude, please solve this problem for Omkar!

An array a of length n is called complete if all elements are positive and don’t exceed 1000, and for all indices x,y,z (1≤x,y,z≤n), ax+ay≠az (not necessarily distinct).

You are given one integer n. Please find any complete array of length n. It is guaranteed that under given constraints such array exists.

Input

Each test contains multiple test cases. The first line contains t (1≤t≤1000) — the number of test cases. Description of the test cases follows.

The only line of each test case contains one integer n (1≤n≤1000).

It is guaranteed that the sum of n over all test cases does not exceed 1000.

Output

For each test case, print a complete array on a single line. All elements have to be integers between 1 and 1000 and for all indices x,y,z (1≤x,y,z≤n) (not necessarily distinct), ax+ay≠az must hold.

If multiple solutions exist, you may print any.

Example
input
2
5
4
output
1 5 3 77 12
384 384 44 44

Note

It can be shown that the outputs above are valid for each test case. For example, 44+44≠384.

Below are some examples of arrays that are NOT complete for the 1st test case:

[1,2,3,4,5]

Notice that a1+a2=a3.

[1,3000,1,300,1]

Notice that a2=3000>1000.

题目大意：

输入一个t表示有t组数据，接下来每一行输入一个n，你需要构造一个长度为 n 的数组，数组内元素可以重复，使得数组内部任何a[x]+a[y]!=a[z]且x!=y!=z ，且每个数组内每个元素不得大于1000。

解题思路：

水题，既然元素可以重复，直接输出n个1即可。AC代码：

#include 
#include 
#include 
#include 
#include 
#include 
#include 
using namespace std;
int main()
{
	int t,n;
	cin>>t;
	while(t--)
	{
		int n;
		cin>>n;
		for(int i=1;i<=n;i++)
		  cout<<1<<" ";
		cout<<endl;
	}
	return 0;
}
