Sudoku

Single Credit

Work the four puzzles handed out in class.

Extra Credit

Write a recursive program to solve sudoku puzzles. Your program will be executed on the 4 puzzles in this assignment. The input file must be called "sudoku.dat" and the output should be on the console. The format for the input is the same as for the in-class exmaple (9 rows of 9 digits, space between each digit).

The main solution part of your code must be recursive, and you must output the number of times your recursive routine is called.

Successful completion of the program will replace your lowest homework grade with a 100.

Submit your code by emailng the TA before March 18.

WARNING!

You are to create this program on your own. The penalty for using other people's code (classmates or the internet) is failing the course.
