  [4, 9, 6, 1,  2 , 5 , 8, 3, 7],
  [2, 6, 9, 4,  5 , 3 , 1, 7, 8],
  [8, 4, 1, 7, 'b','b', 6, 5, 3],
  [5, 3, 7, 8, 'b','b', 4, 9, 2],
  [9, 1, 2, 5,  8 , 7 , 3, 6, 4],
  [6, 5, 3, 2,  4 , 9 , 7, 8, 1],
  [7, 8, 4, 6,  3 , 1 , 5, 2, 9]

first arg is the sudoku in a 2d array

second arg the char for the algorythm whill loking to solve (here the 4 number at the middle of the grid)

the sudoku function return a 2d array of the sudoku bord solved

the display function is for displaying the sudolu solved at the terminal

it can be easly add to a discord bot(if troobling go to my discord)

how it work

there is 3 method use:

the case by case

the algo going to look to each case, seeing if there is a number(changing in loop) that can be place with line and collum of the case and go to the next case and repeating

the egality theorem

it is praticly the same thing that the case by case but more complicate know sudoku verry well for understanding that (u can always asking on my discord)

the line by line and collum by collum

take a line or a collum and try to adding a number in function of line or collum next to it
