Abstract

As with most strategies, you implement “box-line” with two functions: one general that conforms to the type f_ptr_t as defined in def.h and one to handle an individual unit. The general function, box_line() (see Listing 7-1), executes box_line_unit() (see Listings 7-2 and 7-3) for each possible row and column of the Sudoku.
