Codeforces Round #655 (Div. 2) A. Omkar and Completion(构造)

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

An array aa of length nn is called complete if all elements are positive and don't exceed 10001000 , and for all indices xx ,yy ,zz (1≤x,y,zn1≤x,y,z≤n ), ax+ayazax+ay≠az (not necessarily distinct).

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

Input

Each test contains multiple test cases. The first line contains tt (1≤t≤10001≤t≤1000 )  — the number of test cases. Description of the test cases follows.

The only line of each test case contains one integer nn (1≤n≤10001≤n≤1000 ).

It is guaranteed that the sum of nn over all test cases does not exceed 10001000 .

Output

For each test case, print a complete array on a single line. All elements have to be integers between 11 and 10001000 and for all indices xx ,yy ,zz (1≤x,y,zn1≤x,y,z≤n ) (not necessarily distinct), ax+ayazax+ay≠az must hold.

If multiple solutions exist, you may print any.

构造一下,1 3 1 3 1 3…这样即可。

#include <bits/stdc++.h>
using namespace std;
int main()
{
    int t;
    cin >> t;
    while(t--)
    {
        int n;
        cin >> n;
        for(int i = 1; i <= n; i++)
        {
            if(i & 1) cout << 1 << ' ';
            else cout << 3 << ' ';
        }
        cout << endl;
    }
    return 0;
}
