spoj#GRIDSUM1. 2x2 Subgrid Sum Problem (medium)

2x2 Subgrid Sum Problem (medium)

This problem is a higher constraints version of KWACIK (Polish).

Sample case for a=1, b=3 and n=8.

 

You are given a 3x3 grid. You can place an integer m (a ≤ m ≤ b) in each cell.

How many ways are there to place integers in the cells such that the sum of each 2x2 subgrid is n ?

Input

The first line contains an integer T (1 ≤ T ≤ 100), the number of test cases.

On each of the next T lines, you are given three integers a, b and n. (0 ≤ ab ≤ 500, 0 ≤ n ≤ 2000)

Output

For each test case, output a single line containing the number of ways to place integers.

Example

Input:

1
1 2 5

Output:

8

Explanation

There are 8 ways to place integers for a=1, b=2 and n=5.

2 1 2 : 2 1 2 : 2 1 1 : 1 2 1 : 1 2 1 : 1 1 2 : 1 1 1 : 1 1 1
1 1 1 : 1 1 1 : 1 1 2 : 1 1 1 : 1 1 1 : 2 1 1 : 2 1 2 : 1 2 1
2 1 2 : 1 2 1 : 2 1 1 : 2 1 2 : 1 2 1 : 1 1 2 : 1 1 1 : 1 1 1
