Simple sudoku solver written in python

(should have so chosen C or any other proper language for pass by value instead of fighting this pass by reference gubbins :man: :palm_tree:)

Takes a file path as a parameter, file format is akin to csv

• , for delimeter
• x for empty space
• can be presented either as \n terminated rows or as a single line with rows serialized (That’s how positions are stored internally anyway)
• check the 3 example boards
  • 1st is simple solve (no guessing)
  • other two show of recursion solving with guessing
  • minor optimizations are present (guessing from most likely to find)
