What is going on, guys?

I hope you are good and in this exercise, this exercise actually is going to be very similar to the

previous one.

We are going to write an official program that receives a noun from the user.

And what this program is going to do is to calculate and print the sum of all the numbers from one up

to.

OK, that can be divided by three or divided by five.

OK, so previously we had a little bit different program.

It was instead of these or we used and OK, so all the numbers that could be divided by three and by

five and now it's just enough for us if a given number can be divided by three or by five.

And if that's the case, we simply take it and use it inside of our sum as part of the sum and then

print the final sound to the screen.

So if, let's say we received NUM equals to you, I don't know a hundred like previously, then we know

that one, two, three, four, five, six and so on, right up to a hundred.

Then in this case we will take three and also we will take five and also we will take six and all the

numbers that can be divided either by three or by five.

OK, so we will take them and add them to our final some awesome.

And what I want you to notice is that once again here we will do these program, will try this program

in two ways.

The first way will be the trivial option.

OK, so it will be there will be a trivial option and also there will be an efficient option.

OK, so think about two solutions for this exercise.

Try to make some conclusions out of the first one.

OK, of the previous exercise, when we talked about the solution, the optimal solution and the difference

between the optimal and the optimized solution versus the trivial one, and try to come up with two

ideas here.

The first idea should be less trivial, pretty much the same as previously.

And there will be also an optimized solution that you should take into account.

So, yeah, this is it for this video.

Guys, thank you so much for watching.

And let's go solve this exercise together.
