Given two integral m × n matrices A = {aij} and B = {bij}, we define a sequence of matrices SB = {Bk} with B1 = B where, for each k > 1,
.
Write a program that is capable of evaluating SB efficiently.
The input consists of a single test case and is given in the following format:
| m | n | t | |
| a11 | a12 | ⋯ | a1n |
| a21 | a22 | ⋯ | a2n |
| ⋮ | ⋮ | ⋱ | ⋮ |
| am1 | am2 | ⋯ | amn |
| b11 | b12 | ⋯ | b1n |
| b21 | b22 | ⋯ | b2n |
| ⋮ | ⋮ | ⋱ | ⋮ |
| bm1 | bm2 | ⋯ | bmn |
| i1 | j1 | k1 | |
| i2 | j2 | k2 | |
| ⋮ | ⋮ | ⋮ | |
| it | jt | kt |
Bounds on the values are: 1 ≤ m, n ≤ 20; 1 ≤ t ≤ 1000; 0 ≤ aij, bij ≤ 10; 1 ≤ it ≤ m; 1 ≤ jt ≤ n; 1 ≤ kt ≤ 109.
For each t, output bitjtkt mod 1,000,000,007.
