See more:

Format 4 numbers into a 24-hour time (00:00), finding the maximum (latest) time possible, taking into account that the given digits 1,8,3,2 the maximum valid time is 23:18. If not possible, return NOT POSSIBLE.

So for example:

6, 5, 2, 0 would be 20:56

3, 9, 5, 0 would be 09:53

7, 6, 3, 8 would be NOT POSSIBLE

The example function that had to return the time or string looked like this, A, B, C, D being a different number from the comma-separated list above:

function generate(A, B, C, D) {
    // Your code here
}

What I have tried:

Not getting an idea to start with.

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think! Start by thinking about how you would do this manually, and write down the method you'd use. You can then translate this into a software design. You might want to start with a "is this a valid time?" function.

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

You got to take a sheet of paper and a pencil and:
- find every combination ABCD, ABDC ...
- check if possible time
- check if new maximum

We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.

As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.
