01:40This way you will see that you will only have one, two, three, four and five. Nothing else.
01:52This is unique objects.
01:54Okay.
01:56Let's talk about built-in methods.
02:01First of all, add method.
02:03For example, if I test set, underscore set, dot add method call,
02:08and I will say that I will add 100.
02:11If I print it, I will add test set.
02:17I will cut and run.
02:21Now we will see that our previous set was 5,
02:24and this value return.
02:27This method itself is a new method return.
02:33This method will add a new copy value.
02:38For example,
02:41new, underscore set, is equal to test, test, underscore set, dot copy.
02:50So, dot copy basically,
02:52is a method which we call the test set,
02:54which we call the new set.
02:56Okay.
02:57Now, in the new set,
02:58we can call the simple dot add method.
03:02However, again,
03:04because the value value is not returned,
03:07the original value is in change.
03:09So, we will show the value value to the original value.
03:13For example,
03:15I will disengage the copy and test set,
03:18because the change was in change.
03:19So, now I will add the test set.
03:21I will print the test set.
03:22I will print it.
03:23I will print it.
03:24I will print it.
03:26And run it.
03:27You will see that 100 value will be returned.
03:30I will remove it.
03:32Okay.
03:34Because 100 already exists,
03:36it will be added.
03:38Let's see if I can add 5.
03:40Run it.
03:41The 5 cannot be added.
03:42As you can see.
03:43Okay.
03:44Okay.
03:45Okay.
03:46Okay.
03:47Now,
03:48let's see.
03:49Let's see.
03:50Let's see.
03:51Set theory.
03:52Set theory.
03:53For example,
03:54if you have a set A,
03:56and this set B,
03:57what can you do?
03:59What can you do?
04:00Union can do something like that.
04:02Something like that.
04:03Okay.
04:04And two sets can do intersection.
04:06Okay.
04:07And two sets can do difference.
04:10Let's see.
04:11Let's see.
04:12Let's see.
04:13Let's see.
04:14One, two, three.
04:15Just for the sake of simplicity.
04:17So,
04:18we have a test set.
04:19Let's see.
04:20Union.
04:21You can see.
04:22Union.
04:23You can see.
04:24This is a test set.
04:25And one.
04:26We have a test set.
04:27And two.
04:28Use.
04:29Let's see.
04:30And one.
04:31Two.
04:32Three.
04:33Just for the sake of simplicity.
04:35So,
04:36two.
04:37We have a test set.
04:38First,
04:39we can see.
04:40Test.
04:41Underscore.
04:42Set.
04:431.
04:44Union.
04:45Union.
04:46Union.
04:47With test set.
04:482.
04:49Union.
04:50There is a set set.
04:51But,
04:52the common element is redundant.
04:53It is not redundant.
04:54It is not repeated.
04:55For example,
04:56I say,
04:57No.
04:58Just for the sake of simplicity.
05:00Just for the sake of simplicity.
05:01So,
05:02we have a test set.
05:03We have a test set.
05:04I say,
05:05Nine.
05:06Nine.
05:07Nine.
05:08Nine.
05:09Nine.
05:10Nine.
05:11Nine.
05:12Nine.
05:13Nine.
05:14Nine.
05:15Nine.
05:16Nine.
05:17Nine.
05:18Nine.
05:19Nine.
05:20Nine.
05:21Nine.
05:22Nine.
05:23Nine.
05:24Nine.
05:25Nine.
05:26Nine.
05:27Nine.
05:28Nine.
05:29Nine.
05:30Nine.
05:31Nine.
05:32Nine.
05:33Nine.
05:34you see the same result union
05:41this is intersection
05:44union is just join
05:48intersection will return
05:51which are common
05:53intersection
05:55test one test two
05:57as you see
06:00common
06:02nine
06:04let's say
06:05seven
06:06seven
06:07common
06:08now
06:09you will be
06:10common
06:11nine
06:12and seven
06:13basically
06:14if I go back
06:16diagram
06:17this intersection
06:20this region
06:22return
06:23this set
06:24a
06:25this
06:26common values
06:27return
06:28however
06:29union
06:30two set
06:32union
06:33then
06:35this area
06:36return
06:37this
06:38area
06:39return
06:40intersection
06:41uniquely
06:42return
06:43as a single region
06:45return
06:46you understand
06:47intersection
06:48is
06:49this
06:50line
06:51uniquely
06:52set
06:53return
06:54this
06:55is
06:56difference
06:57difference
06:58basically
06:59you can see
07:01intersection
07:02you can see
07:03one
07:04two
07:05three
07:06and
07:07eight
07:08you can see

07:23eight
07:24basically
07:25set

07:32exist
07:33set
07:34one
07:35set
07:36two
07:37order
07:38that is
07:39very important
07:40for example
07:41if you
07:42intersection
07:43with
07:44set
07:45two
07:46and set
07:47one
07:48result
07:49will be
07:50different
07:51so
07:52you can see
07:53union
07:54difference
07:55because
07:56if
07:57one
07:58result
07:59will be
08:00different
08:01as you
08:02see
08:03one
08:04two
08:05three
08:06okay
08:07so
08:08congratulations
08:09guys
08:10you have
08:11done
08:12the data
08:13structure
08:14completely
08:15give
08:16yourself
08:17a big
08:18tap
08:19okay
