Months ago I was trying to debug why this[0] solver didn't quite work. If someone wants to spend some time debugging it, you're welcome to it.
It's a Rust compile time Sudoku solver. It solves the almost complete puzzle, not the "real" puzzle.

- yorwba 2y agowhile grid[index] == 9 || grid[index] != 0 { is equivalent to while grid[index] != 0 { so when you backtrack, you always backtrack all the way to the beginning. I think you want while grid[index] == 9 || initial_grid[index] != 0 { grid[index] = initial_grid[index]; or something to that effect.
