Problem Description

Given a positive integer n and the odd integer o and the nonnegative integer p such that n = o2^p.


Example

For n = 24, o = 3 and p = 3.


Task

Write a program which for each data set:

reads a positive integer n,

computes the odd integer o and the nonnegative integer p such that n = o2^p,

writes the result.

 

Input

The first line of the input contains exactly one positive integer d equal to the number of data sets, 1 <= d <= 10. The data sets follow.

Each data set consists of exactly one line containing exactly one integer n, 1 <= n <= 10^6.

 

Output

The output should consists of exactly d lines, one line for each data set.

Line i, 1 <= i <= d, corresponds to the i-th input and should contain two integers o and p separated by a single space such that n = o2^p.

 

Sample Input

124

 

Sample Output

3 3

 一开始 常规暴力，怎么该都超时。百度了一下。教训是，数学一一般都有规律，或技巧可言。

#include<iostream>#include<cmath>using namespace std;int main(){int n,N;cin>>N;for(int k=0;k<N;k++){cin>>n;int count=0;while(n%2==0){count++;n/=2;}cout<<n<<" "<<count<<endl;}return 0;}
