Tips on solving programming problems




Either you are solving problems from the exercises in your books or from online course or in an interview, these tips will guide you to tackle them.

1. Always bring pen paper before beginning to solve a problem, it gives a better visualisation. Don't solve any problem without pen and paper. I have a long notebook, it is filled with problems analysis. Remember, no pen and paper no solution!

2. Read the problem over and over again until you understand it. If you don't understand the problem, what are you going to implement? Is it not better you move to the next problem if there is any or continue to read to understand until you understand it, if there is no more problems or even rest your case. Remember a doctor cannot cure a disease he knows nothing about. For you to solve a problem you must understand it, if you can't it then humbly rest your case, nobody is going kill you for not tackling it.

3. Don't be intimidated by how hard the problem appears. Don't allow your heart to pop out, hold your peace and start reading and analysing the problem step by step with pen and paper. Examine every word critically and try understand what they mean, when you have understood it, pen your pseudocode down, and start implementing it. If it works, congratulations! But if it doesn't work, try yet another algorithms. Remember, you must not solve all the problems in the world, even expert coders can fumble on many problems which non-expert can solve, it all depends on your thinking curve at that moment. Since no one is going to slaughter you for not solving the problem, why should you bother yourself?

4. Having tried a lot without being successful, seek help if you can. Remember any problem you face many people out there might have faced the same problem, so don't die in isolation you better seek help.
NOTE:
I'm always against seeking help for solution for a problem especially at your learning and practising time. If others can do it, you yourself can do it too, always have that in mind. Remember, that you can't solve a problem today doesn't mean you can't solve it tomorrow, as far as you continue to increase in learning algorithms and data structures, you will come back to solve even the most difficult problem to you at the moment. But if you are building a project and not just practising, you can Google the problem, there might be solution which you can just copy and paste for your project and continue.
Good luck!

@progeek37, I figured the problem with my strong password detector program. I didn't read the question correctly. It states write a function and I've been doing it without a function. Will rewrite it to give out the correct answer.
