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.
