MathDoku/CalcuDoku/KenKen/KenDoku arithmetic puzzle solver.
The solver reads the following input format from text file or string:
n m x_0_0 x_0_1 ... x_0_n-1 x_1_0 x_1_1 ... x_1_n-1 ... x_n-1_0 x_n-1_1 ... x_n-1_n-1 0 op_0 v_0 1 op_1 v_1 ... m-1 op_m-1 v_m-1
Where:
| n | Size of MathDoku grid length. |
| m | Number of cages. |
| x_(i)_(j) |
Cage index in the grid layout at row (i) and column (j). Index starts with 0. |
| op_(i) |
Arithmetical operation to perform on the cage at index (i). Valid operations are:
|
| v_(i) | Value of the arithmetical operation on all cell values in the cage. |
Sample 4x4 MathDoku problem with 6 cages:
4 6 0 0 0 1 2 2 3 1 4 2 1 1 4 2 5 5 0 * 24 1 + 10 2 * 24 3 + 3 4 - 1 5 / 4
Sample solution for the problem above:
========= |3 4 2 1| |4 1 3 2| |1 2 4 3| |2 3 1 4| =========
