Assignment 1

Sudoku Solver

Is it a program that solves Sudoku puzzles(9X9) using Bruteforce algorithm. Either the user can pass a Sudoku files as an input or enter the values manually. Moreover, the file or the manual entry should have strictly 9 rows and 9 columns in them. Lastly, all the cells should be separated by a space and the cells that needs to be solved should have 0 in them as their value.

The original source code can be found at Link

LOGIC

In this program the Bruteforce algorithm first put 1 in the first cell and then check if it is violating any rules. If yes, then it increment the value to 2 and check again (The value can vary from 1-9) until it finds the appropriate value. After finding a suitable value for the first cell, it moves to the second cell and put 1 in there and again check again if it violating any rules. If it is discovers that 1 is not allowed in that cell, then the algorithm will increment it to 2 and check again.

Compiling the program
  g++ -std=c++0x -pg solver.cpp checks.cpp checksolution.cpp -o a
  a fileName


-pg directs the compiler to include the executable code required for profiling.

-o directs the compiler to name the executable a.


If we run the sample-puzzle-1 (level- easy) file the output will be:

Input 0 6 0 0 0 0 9 7 2

       0 5 0 0 0 2 0 0 3
       0 7 0 3 9 0 5 0 0
       2 0 0 0 0 5 4 0 8
       0 0 0 0 0 0 0 0 0
       3 0 1 8 0 0 0 0 6
       0 0 4 0 2 3 0 8 0
       7 0 0 9 0 0 0 2 0
       9 2 5 0 0 0 0 4 0
