You are given a positive integer x. Find any such 2 positive integers a and b such that GCD(a,b)+LCM(a,b)=x.

As a reminder, GCD(a,b) is the greatest integer that divides both a and b. Similarly, LCM(a,b) is the smallest integer such that both a and b divide it.

It's guaranteed that the solution always exists. If there are several such pairs (a, b), you can output any of them.

Input

The first line contains a single integer t (1 ≤ t ≤ 100) — the number of testcases.

Each testcase consists of one line containing a single integer, x (2 ≤ x ≤ 10^9).

Output

For each testcase, output a pair of positive integers a and b (1 ≤ a, b ≤ 10^9) such that GCD(a,b)+LCM(a,b)=x. It's guaranteed that the solution always exists. If there are several such pairs (a, b), you can output any of them.

Example

Input


2
2
14


Output


1 1
6 4

Note

In the first testcase of the sample, GCD(1,1)+LCM(1,1)=1+1=2.

In the second testcase of the sample, GCD(6,4)+LCM(6,4)=2+12=14.
