* The L_Sudoku holds all the information of the current state.

|
|
* The input to sudokuCreate() is a file with any number of lines
|
||
|
|
* starting with '#', followed by 9 lines consisting of 9 numbers
|
||
|
|
* in each line. These have the known values and use 0 for the unknowns.
|

|
|
* Blank lines are ignored.
|
||
|
|
*
|
||
|
|
* The %locs array holds the indices of the unknowns, numbered
|
||
|
|
* left-to-right and top-to-bottom from 0 to 80. The array size
|
||
|
|
* is initialized to %num. %current is the index into the %locs
|
||
|
|
* array of the current guess: locs[current].
|
||
|
|
*
|
||
|
|
* The %state array is used to determine the validity of each guess.
|
||
|
|
* It is of size 81, and is initialized by setting the unknowns to 0
|
||
|
|
* and the knowns to their input values.
