#Q195. 「一本通 6.1 例 1」序列的第 k 个数

「一本通 6.1 例 1」序列的第 k 个数

Description

BSNY is learning about arithmetic and geometric sequences. Given the first three terms of a sequence, it can be determined whether it is an arithmetic or geometric sequence. Now, given the first three terms of a sequence, which is either arithmetic or geometric, can you find the value of the kk-th term? If the value is too large, take modulo 200907200907.

Input Format

The first line contains an integer TT, indicating the number of test cases.

For each test case, input the first three terms a,b,ca, b, c, followed by kk.

Output Format

For each test case, output the value of the kk-th term modulo 200907200907.

Sample 1

The first sequence is arithmetic, and the second is geometric.
