Hi, ladies and gentlemen, and welcome to another video in our amazing programming course.

And in this exercise, what I would like to ask you to do is simply to create two programs okay.

They should not be very complicated, but still they are kind of nice to practice.

So these two programs are going to consist of two parts.

The first program is going that you are going to develop is a program that all he does is simply eat

prince, all the unique elements in an array to the screen.

So for any given array that you will get, OK, let's say you created just some program with, let's

say, 10 values.

So your task is to iterate over all of the elements of this array and ask yourself if this element is

unique or not.

If it is unique, printed, if it's not unique, then do not print it.

So for example, let's say you have something like that.

Okay, so let's say you've got an array of values five seven three four five six eight nine, I don't

know eight and then goes like three.

So you ask yourself a simple question is this five a year?

And in any place here?

Else?

Yes, it is.

So we do not brain dead since it's not unique.

But on the other hand, seven is a value that appears only here.

So that's a unique value.

That's why we will print it and so on and so forth.

So for any given array, you will need to print all of the unique elements.

The second part for this exercise may be done in two different programs.

Or maybe it can also be done in just one program.

Well, that depends.

OK, well, we'll see what we will do in the solution.

You can do it in both of them in just one exercise and one program.

You can do it in two different programs.

I'm probably I will combine the solution to be in just one program.

So then the second part is to count the total number of unique elements in an array.

So first of all, we printed out all of the elements.

But meanwhile, we also created some counter to count the number of unique elements in the array.

OK, so that's what we are going to do and basically, that's what you are going to do.

So my recommendation is before moving forward trying to solve this exercise in your realm, try to think

about what should be used here, what loops, what conditions and what everything else should be used

here.

So, yeah, so there this way, you will be able to solve it on your own.

And once you've tried and you see some success or maybe you something didn't happen to be so successful,

you can always move on to the next video, which is not mandatory, but it's here to assist you and

let you see if you are doing quite well.

So good luck and I'll see you in the solutions video by.
