1
00:00:05,860 --> 00:00:06,460
Hey everyone.

2
00:00:06,670 --> 00:00:07,450
So don't.

3
00:00:07,450 --> 00:00:15,090
The boat also known the next step is the availability of free space is a space is free or not.

4
00:00:15,700 --> 00:00:19,650
So for that also we need to define functions here.

5
00:00:19,720 --> 00:00:21,700
Because again we didn't know where to edit them.

6
00:00:22,240 --> 00:00:31,000
So we will define functions like space is free.

7
00:00:31,000 --> 00:00:34,330
And that one is for when space is free.

8
00:00:34,330 --> 00:00:40,930
And we will require a barometer that is again the position because the space will be free for a particular

9
00:00:40,930 --> 00:00:41,530
position.

10
00:00:42,190 --> 00:00:46,880
And in that case it will just return that the space is free.

11
00:00:46,990 --> 00:00:50,550
On that particular position that is board position.

12
00:00:50,770 --> 00:00:54,210
And this will be an empty string at that point.

13
00:00:55,030 --> 00:00:57,750
So it will be done through.

14
00:00:58,420 --> 00:01:03,530
So remember this thing that when the space is free the function is returning true.

15
00:01:03,610 --> 00:01:06,440
And we are going to need that particular value.

16
00:01:06,490 --> 00:01:08,580
That is the true here.

17
00:01:08,620 --> 00:01:12,330
So this one is for when this space is free.

18
00:01:12,510 --> 00:01:15,230
And now what about when space is not free.

19
00:01:15,280 --> 00:01:17,130
So we also need to define that one.

20
00:01:17,350 --> 00:01:22,290
So for a little time just closed these functions and there we go.

21
00:01:23,460 --> 00:01:31,660
Now they define this one after these because in starting let we have only these main functions that

22
00:01:31,660 --> 00:01:33,800
is defined for devoting.

23
00:01:33,850 --> 00:01:35,080
This is done is also required.

24
00:01:35,110 --> 00:01:38,520
But this one is just for like my space is not free.

25
00:01:38,920 --> 00:01:42,330
So this function is something like we named this one.

26
00:01:42,520 --> 00:01:49,300
Like is board full and make this also.

27
00:01:51,370 --> 00:01:56,800
And this is not so so that it will properly define the.

28
00:01:56,820 --> 00:01:57,690
Different words.

29
00:01:58,210 --> 00:02:00,010
So is board full.

30
00:02:00,670 --> 00:02:03,810
And then again we will lend a parameter.

31
00:02:04,450 --> 00:02:09,920
But in this case we just need the board because the board is going to be filled.

32
00:02:10,270 --> 00:02:13,090
And then if

33
00:02:17,370 --> 00:02:27,230
a board and naval user attribute that is kind empty string created then.

34
00:02:27,240 --> 00:02:32,610
But in that case return false.

35
00:02:32,830 --> 00:02:35,760
Let me do this and first and I will explain you.

36
00:02:35,780 --> 00:02:42,280
That also defaults on boolean then a device

37
00:02:45,430 --> 00:02:46,240
return true.

38
00:02:47,470 --> 00:02:55,240
So here what I have done I have taken in the name that is is board full with the parameter board and

39
00:02:55,290 --> 00:03:00,730
in the case then board don't count of empty strings.

40
00:03:00,730 --> 00:03:03,370
This can function is used to count that particular value.

41
00:03:03,370 --> 00:03:08,830
And that what we are counting here the empty strings when that empty strings are greater then but what

42
00:03:08,830 --> 00:03:09,750
that means.

43
00:03:09,970 --> 00:03:17,030
That means there is some space in that particular board like head discount will be five so here we have

44
00:03:17,030 --> 00:03:22,870
the value five that is greater than one which means that we have vacant space.

45
00:03:22,880 --> 00:03:27,530
So in that case for this particular function this function is checking whether the board is full or

46
00:03:27,530 --> 00:03:28,220
not.

47
00:03:28,250 --> 00:03:30,290
So here the board is not full.

48
00:03:30,290 --> 00:03:32,480
So it will return false.

49
00:03:32,570 --> 00:03:35,120
Otherwise in all cases it will return true.

50
00:03:35,960 --> 00:03:41,790
So that's about the freeze and not fully.

51
00:03:42,080 --> 00:03:47,390
So we have also checked this space is the space is free or not free.

52
00:03:47,390 --> 00:03:51,980
Now what about the veena that how we can check diviner.

53
00:03:52,580 --> 00:03:58,550
So as I have told you go with maybe this video but this one is a little task for you tried to find out

54
00:03:58,550 --> 00:04:05,470
how we can check that who is winner for a tic tac toe and see in the next video the dissolution of this

55
00:04:05,470 --> 00:04:05,750
one.
