Why don't you put some effort from your side?

Here is what is expected by enquirers:
1. TRY first what you want to do!
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.

Solution 1

This is a real beginner type question.
Your algorithm will require that you start with the highest value note.

you will need a loop of some sort. Divide the amount outstanding by the note valid e.g 1500 / 1000 = 1.5 therefore you requre 1 x 1000 note.
The remained (0.5) is multiplied by 100 giving your 500. Divide that by 500 e.g 500 / 500 = 1 therefore you require 1 x 500 note.

Final result is you will need 1 x 1000 note and 1 x 500 note.

We don't simply provide you free easy code.
We explain or correct your code. We give hints and spot errors.
Okay?
