Problem Description

A tourist gets lost in the desert with n liters of water. He drinks positive integer units of water each day.

Write a program to calculate how many different ways the tourist can drink up the water.

Input

The first line contains the number of test cases

T(T≤10).
Next

T lines contain the number

n(1≤n≤1000000) for each test case.

Output

Output consists of

T lines.
Each line contains the binary number which represents number of different ways to finish up the water specified in the test case.

Sample Input

1
3

Sample Output

100

Hint
3 liters of water can be comsumed in four different ways show in the following.  
1. 1 1 1  
2. 1 2  
3. 2 1  
4. 3  

If we write 4 in binary, it's 100.

AC源码:

#include <iostream>
using namespace std;

int main()
{
	int T,n;
	cin>>T;
	while(T--)
	{
		cin>>n;
		cout<<"1";
		while(--n)
			cout<<"0";
		cout<<endl;
	}
	return 0;
}
