So for my homework, one of my problems asks me to write a program that reads a text file and determines if it is a correct solution to a sudoku puzzle. I'm not totally sure what to do.
I think I'm supposed to write it to an array then work from there using if statements, but how do I take from the text file and put it to a 2 dimensional 9x9 integer array?
The second problem asks to do an Ackerman function, I don't really know what that is, my professor gave us an example of one using n and m, and asks to print the number k which doesn't appear in the function.
This doesn't make much sense. All help would be appreciated.
