Hello there, ladies and gentlemen.

And in this video, what we are going to do is, first of all, to use our visual studio in this case,

I think that's 2019.

And that's maybe a different idea from whatever you're using.

Or maybe that's the same.

It doesn't really matter.

Okay, since all of the code is going to be written just the same way, the same way it was written

previously.

OK.

Any of these exercise, we are going to practice our knowledge.

OK, so let's say our exercise is going to be as the following.

So exercise ready to practice in what we have to do in this exercise is very simple, yet it's very,

very interesting.

What we need to do is to write a program.

OK, so write a program, a program that all it will do.

What these programs should do is write a program that should.

Rotate.

OK.

That should rotate.

Let's use left rotate left a given array, a given array by one, by one position.

OK, so these exercises basically the preparation for more complicated exercises, but still it's very

important to know how to solve it.

So writing a program that should rotate left a given away by one position.

So let's say you were given with this array.

Let's take it like a small one.

Let's go like five four and go with seven and three.

So our task is to rotate left.

OK, we want to rotate the array left, and that's going to look like this.

OK, so we are going basically to take these value of five and put it right here and all of the other

elements to take them to the left.

So that means that after the operation.

OK, so that's before that's did before, and that's the after.

So after we will have four, seven, three and five, so that's what we've done in the rotation.

So that's before, that's after.

And you need to write a program, OK, that can initialize this array.

Some arbitrary array with four elements just for simplicity doesn't really matter.

And then all it should do is rotate to the left by one element.

So take your time.

Think about the algorithm, the solution that may solve this exercise, and once you're done comparing

it with the results, and let's move on.

OK, so get ready.

Let's start.

Yeah, we go.

Good luck.
