There are nn digital panels placed in a straight line. Each panel can show any digit from 00 to 99. Initially, all panels show 00.

Every second, the digit shown by each panel increases by 11. In other words, at the end of every second, a panel that showed 99 would now show 00, a panel that showed 00 would now show 11, a panel that showed 11 would now show 22, and so on.

When a panel is paused, the digit displayed on the panel does not change in the subsequent seconds.

You must pause exactly one of these panels, at any second you wish. Then, the panels adjacent to it get paused one second later, the panels adjacent to those get paused 22 seconds later, and so on. In other words, if you pause panel xx, panel yy (for all valid yy) would be paused exactly |x−y||x−y| seconds later.

For example, suppose there are 44 panels, and the 33-rd panel is paused when the digit 99 is on it.

 

 

The resulting 44-digit number is 10901090. Note that this example is not optimal for n=4n=4.

Once all panels have been paused, you write the digits displayed on them from left to right, to form an nn digit number (it can consist of leading zeros). What is the largest possible number you can get? Initially, all panels show 00.

Input

The first line of the input contains a single integer tt (1≤t≤1001≤t≤100) — the number of test cases. Each test case consists of a single line containing a single integer nn (1≤n≤2⋅1051≤n≤2⋅105).

It is guaranteed that the sum of nn over all test cases does not exceed 2⋅1052⋅105.

Output

For each test case, print the largest number you can achieve, if you pause one panel optimally.

Note

In the first test case, it is optimal to pause the first panel when the number 99 is displayed on it.

In the second test case, it is optimal to pause the second panel when the number 88 is displayed on it.

解题说明:水题,贪心算法,第一个数肯定为9,然后依次递减循环输出。


#include<stdio.h>
#include<string.h>

int main() 
{
	int t, i;
	long int n, j;
	scanf("%d", &t);
	for (i = 0; i<t; i++) 
	{
		scanf("%ld", &n);
		printf("9");
		if (n>1) 
		{
			for (j = 1; j < n; j++)
			{
				printf("%ld", (j + 7) % 10);
			}
		}
		printf("\n");
	}
	return 0;
