AP3  AP  Complete The Series v2
After solving "AP  Complete The Series (easy)" very fast, Lucifer decided to make it little more interesting.
He said
He will be give you the 3rd term , 4th last term and the sum of the AP series. You need print length of the series & 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' ,'4Lastterm' and 'sum'
3term  is the 3rd term in the series and
4Lastterm  is the 4th last term in the series and
sum  is the sum of the series.
Output
For each input of the test case, you need to print 2 lines.
fist line should have 1 value number of terms in the series.
2nd line of the output should print the series numbers separated by single space.
Example
Input:
1
3 7 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)

@encrypted: You don't need BigInt Class to solve this problem in C/C++. This problem has many precision issues which should be carefully handled. Rest is straight forward. e.g. use sqrtl instead of sqrt,ceill,floorl,llrintl of <cmath> in C++. Use doubles & convert to long long when required. :)
