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.
