Hello welcome everyone in this video we're gonna, look at song order.

A brain function in are all of this saw order and right there in ascending order by default before here means, if you use a keyword, this decreasing is equal to force.

So you will see that in ascending order means that is my solid starting from smallest, bigger and then finally, because we'll be at the end.

Okay, on the right hand side.

So when we do the operation so, although over and we have to take note of two things- one is the actual value and then the other is the position in the vector in our the position start with one as up as opposed to other programming language, where the index is 0 in our the index is 1.

Here is a vector or sequence of numbers: 44, 11, 55, 33 and 22 for the voice at position.

1 of the vector X 55 is a position tree of vertex and 22.

A position 5 of vector X.

This vector have five elements.

Ie the length of the vector is far.

Let's start with salt.

Here is the element of X.

When we saw X, we called it is going to go for the ascending order.

A small to large eleven is a smallest and 55 is the largest and they are in.

The ascending order is easy, so in this case were sorting, do sweet actually and the default is in ascending order.

Ie same thing as using the keyword decreasing equal force, I even wanted to sort X decreasing for ya this now after something, you can print the vector X again, you will get the same origin over the X.

Ie sorting would not destroy the original vector, X expressive.

Okay.

Now, let's look at order same thing.

We're gonna have the vector X and then we are gonna call the building function.

Order setting X is going to return you to 5 4 1 3 you.

So what are these number? This number or the position here too, means his elves like salt.

So it's gonna return as eleven right.

It's not gonna return.

You eleven is not written you.

The position of 11, which is 2.

The next number is 5, is 22, is a written in 22.

So, with a new, the position of 22 same thing: position of the d3 position of 24 and position of 54.

So these are the position they were written so salt and order one returns, the actual value, so that value the other way is written in the sorted values position.

Now, if you were to honor X, so get Q the subscript or the index of X sorted in ascending order and then, if you print out X with square bracket, you get the same thing as so X, so we have seen so that we have seen order next up.

We will look at rank okay, original vector X.

So if you will solve X in ascending order, small small to big.

This should be the position of the vector X okay.

So what ranks will rang X? So 44 is right.

Number four is a right.

It's ranked number four! So it's opened in 44 you print the rent, which is 411.

That's one level is the smallest one running the ball.

55 here and number 533 here.

Randomly 322 okay, so ran again.

Give you the position, not position of the array or like the position of is ranking, like you know, in sports first position.

Second position at that position, so it is not ranking, isn't looking at the index just like the order, but this is like looking at the the subscript or the index of the after.

It is rang how forth is around four four and number four.

So when you pre know is a preening football.

You bring this number the rain of 44.

Now, if you look at the rank and order both print out the position of the vector order of X, bring out the position where the smallest number is a is original position.

This is the position position where I was right.

What bring you the ranking of the value inside, giving you the value it gives you the the the rank.

That's why they are different, but they are all the same.

Here's the our program.

We use our own money, Paul, open your browser and point to HTTP colon, slash, slash, Rd, RR, dot, io / snippet our online create a vector for a foil.

Every 5 days, return to assign to X code, remove building functions on X, so clean up this meeting.

Then you bring out the original like the X.

It is the same one.

Next you call the building function, order it's going to bring out the order of X, which is Scarpino.

Instead of reading the actual value is going to bring out the the subscript of the minimum increasing.

Do you hit the maximum share? Your business? You go to the X of 3, you get the the largest value.

Let me show that calling order will get you the ordering of X and then, when you call X subscript that you know the same as calling son of X in as any water and rain open up everybody's ready, okay, side note in the business video, we say that the default is in the increasing order.

If you wanna do in the descrition order from big to small use, the keyword decreasing equal true course on for all the same thing before right.

If we do this, we can error.

So you cannot do that in right.

We are going to provide you the our program in a in the description, so you guys can look at it open your browser point browser to this URL cut the program and paste it on your browser and running.

If you notice in the program that we provide, you will see less - replace this list with less than sign, because YouTube Auto allow us to put in this often in character.

So, therefore we have to replace this with less and for you guys, you have to replace this back to the last time before running the Chrome done.

Thank you for watching hope.

The video is helpful.

Now you know the difference between really insult order and right salt will get you the sort of value the default is.

The ascending order order.

Is that giving you the actual value? It's gonna give you the position of where the value is a is going to get you.

The the index of the original vector rank will get you not the value again.

You'll get you this subscript.

If you were to rank from smallest Biggers if you're new to the channel.

Please subscribe.

So you do not miss upcoming video and before you go, please don't forget the heat or smash the like button.

I'll see you guys again next time, bye, bye thanks again for watching see you then bye.
