All language subtitles for 20. Efficient Calculation Example - Question

What is going on, guys?

And welcome to another video in our amazing program, of course, and as always, my name is what this

is Alphatech And we are talking about what are we talking about?

We are talking about a program that receives an integer and they think the jury's called icks.

OK, nothing complicated, though, but so far we know how to receive an integer.

But now what we have to do is to make this program calculate and print what you print, calculate and

print X in a power of two, X in a power of four, X in a power of six and X in the power of eight.

OK, so we simply have to get some number.

For example, let's say three, OK, and then we know that three in the power of two is just nine and

three in the power of four will be probably nine multiplied by nine or three, multiplied by three,

multiplied by three and once again multiplied by three.

Which give us which should give us about eighty one, if I'm not mistaken.

So that's basically what we have to do, this exercise just to print these results to the screen.

But there is a catch, a little catch in these six are science.

And basically what it is, it's simply that the calculation should be done efficiently.

So we know that probably if we apply some mathematical operations, some good operations, maybe we

can save some computation time and make it much more efficient.

Then let's say we have here two approaches, that one approach will be much slower while the other will

be much more optimized.

So take a couple of moments to think about it.

Probably come with also both of the solutions, the trivial solution and also the optimized solution,

which will or should make these program, these calculation more efficient.

So give it a try and I'll see in the Solutions video.
