## AP2 - AP - Complete The Series (Easy)

no tags

Arithmetic and geometric Progressions are 2 of the well known progressions in maths.

Arithmetic progression(AP) is a set in which the difference between 2 numbers in constant. for e.g., 1, 3, 5, 7, 9 ... In this series the difference between 2 numbers is 2.

The task here is very simple indeed.

You will be given the 3rd term , 3rd last term and the sum of the series. You need print length of the series and the series.

### Input

First line will contain a number indicating the number of test cases.

Each of the following t lines will have 3 number '3term', '3Lastterm' and 'sum'

3term - is the 3rd term in of the series and

3Lastterm - is the 3rd term in of the series and

sum - is the sum of the series.

### Output

For each input of the test case, you need to print 2 lines.

First line should have 1 value - the number of terms in the series.

2nd line of the output should print the series numbers separated by single space.

### Example

```Input:
1
3 8 55

Output:
10
1 2 3 4 5 6 7 8 9 10```

NOTE:

• In all the test cases, all the series elements are positive integers.
• The series will have at least 7 elements.
• number of test cases <=100.
• All the numbers will fit in 64 bits (long long in C)

## Code Examples

int num=sum*2/(t1+t2);
cout<<num<<endl;
long long diff=t2-t1;
long long gp=diff/(num-6+1);
long long start=t1-2*gp;
for(int i=0;i<num;i++){
cout<<start<<" ";
start+=gp;
}
}
return 0;
