Some Lessons

There are some important ideas in algorithm and program design:

1. There is more than one way to do it.
   Your first task is to find a correct algorithm. After that, strive for clarity,simplicity, efficiency, scalability and elegance. Good algorithms and programs are like poems of logic. They are a pleasure to read and maintain.
2. Be the computer.
   Grand Master Turing once dreamed that he was a machine. When he awoke he exclaimed: "I dono't know whether I am Turing dreaming that I am a machine, or a machine dreaming that I am Turing!"
3. Generality is good.
4. Don't reinvent the wheel.
   As you are learning to program, designing from scratch is great experience. Truly expertprogrammers, however, know when to borrow.
