Why are only two test cases unlocked?

Question

After solving a problem, when I run the code only the first two test cases are unlocked. Many of them seem locked. What's the problem? Is it normal?

Answer 1

It's very normal.
Think of a real-life scenario, you don't know all the values which a user could enter. Your program needs to handle them.
So, you need to learn as a programmer how to write good codes which solve or deal with all inputs for your problem.
A comment from another user also wrote that it would be very easy for users here to simply program a series of if/else if/else cases to solve every solution. And that's not learning anything more in programming.

Think outside of hard coded solutions and aim for good programming practises to solve the problem properly.
