#include <iostream>

using namespace std;

int main()

{

int f;

cin>>f ;

int a[5] ,d ,r;

for(int i=0;i<=f;i++)

{

cin>> a[0] >> a[1] >> a[2] >> a[3] ;

if(a[2]-a[1]==a[3]-a[2])

{

d=a[3]-a[2];

a[4]=a[3]+d;

cout<< a[0] <<" "<< a[1] <<" "<< a[2]<<" " << a[3]<<" " << a[4] << endl;

}else

{

r=a[3]/a[2];

a[4]=a[3]*r;

cout<< a[0] <<" "<< a[1]<<" " << a[2]<<" " << a[3]<<" " << a[4] << endl;

}

}

} 

for(int i=0;i<=f;i++)

這裡會跑 i = 0, 1, ..., f 共 f + 1 次
