I wanted to write a sudoku solver from a very long time. I had over estimated the problem; rather the solution, to a very great extent. It was sattvik who helped me to come out of that feeling. His words, 'simple validation and backtracking will do the job' made me think for sometime and i got the solution.
I was really happy once i completed writing the code. started at 1 in the noon. At 5:30, i had something which could be compiled, but it didn't work as usual . debugged it till 8:30 to get the code working.
