All language subtitles for 13. Continue (Upgrade) Rotate Left a given array by N positions - Question

All right.

Welcome back, ladies and gentlemen, and we proceed and we improve from our previous exercise.

And we've talked about how we can write a program that should rotate left eye given away by just one

position.

Any of these exercise what you are required to do since you already know, or at least you should be

familiar with the topic you discussed right here in the previous solution.

Now you need to write a program that should rotate left a given away by not by one position, which

we know how to do it, but rather by any positions.

OK, so and positions.

That's the difference between this exercise and the previous one.

So in the previous one, let's do it like with the same calories.

OK, so it's and positions.

In the previous exercise, that was just one.

But now we will read from the user, OK, or say, I can also define some and on my own or really from

the user.

Whatever you prefer for now, it's it doesn't matter.

You can create also additional variable.

I'm going to go with some example like defining and define and to be equal to, let's say, two or three.

So if and it will be equal to two.

So our task would be to take these five.

And to put it right here, OK, so better safe, I'm going to show you the final result.

It should be like we rotated all of them twice two positions to the left.

So five went and then four went and then seven went two positions.

So seven will be here.

Three went also two positions.

It should be here.

Or went also two positions, one and two for us should be here in five went.

Also two positions and now it's going to be like one and two.

OK, so that's the before.

That's how it looks like before.

And that's how it looks like afterwards.

So the question is, how can we make it kind of general because an can be specified with a different

value as well as it can be received from the user is a different value.

Right?

Using some input function.

So if and was three, so we had to rotate everything by three and so on and so forth.

So your task, OK, is basically to let's go this way, take advantage of everything that you've developed

so far in their previous exercise.

OK, so in the previous exercise, we knew how we can rotate to the left a given away by one position.

Now we need to kind of upgrade this program to support the rotate left by end positions.

So think about it, tried to run these programs, try to create something on your own.

Okay.

Don't give up.

It's very important because that's the actual process of learning.

OK, not only are watching me solving these exercises one after the other, I know it's kind of nice.

But it's really important that you will try also solving on your own.

Okay, yes.

So good luck and I will see you in the solutions video to compare our results.

Goodbye.
