00:00:00,210 --> 00:00:03,810
Before we start, did you try solving the workbook yourself?

2
00:00:03,840 --> 00:00:09,600
If not, please click the link in the resources folder and follow the instructions for this workbook.

3
00:00:10,820 --> 00:00:12,600
Welcome to Work Book 5.7.

4
00:00:12,620 --> 00:00:15,890
It tells us to see learn the part for detailed instructions.

5
00:00:15,890 --> 00:00:20,930
Let's do just that task One is to make a4a loop that counts from 0 to 18.

6
00:00:21,050 --> 00:00:22,850
So we will say four.

7
00:00:24,110 --> 00:00:29,990
The counter is going to start an AI equaling zero and the four loop is going to keep running so long

8
00:00:29,990 --> 00:00:32,540
as AI is smaller than 19.

9
00:00:34,800 --> 00:00:40,440
Once we reach 19, we want the loop to break and then we'll say I plus, plus.

10
00:00:41,890 --> 00:00:45,250
And every time the loop runs, we're going to print.

11
00:00:47,290 --> 00:00:48,850
I guess, the number itself.

12
00:00:49,660 --> 00:00:49,960
All right.

13
00:00:49,960 --> 00:00:52,330
It's not worth visualizing the runtime just yet.

14
00:00:52,360 --> 00:00:59,120
Task two is to set up an if ls if L statement, which checks if a number is a multiple of three.

15
00:00:59,140 --> 00:01:00,790
Market forces five.

16
00:01:00,790 --> 00:01:01,990
Market Buzz.

17
00:01:02,020 --> 00:01:05,680
If it's a multiple of three and five market forces Buzz.

18
00:01:05,800 --> 00:01:13,990
Easy enough now for a number to be a multiple of three, let's say like nine, 12 or 15.

19
00:01:14,380 --> 00:01:19,390
All of these numbers divided by three return a remainder of zero.

20
00:01:19,780 --> 00:01:21,700
Here we can say if.

21
00:01:22,930 --> 00:01:25,660
The number that's currently being iterated through.

22
00:01:25,660 --> 00:01:30,400
If that number modulus three, returns a remainder of zero.

23
00:01:32,800 --> 00:01:36,880
Then we mark this number as fiz.

24
00:01:41,750 --> 00:01:49,190
But if the current number being iterated through, if dividing it by five returns a remainder of zero.

25
00:01:50,160 --> 00:01:52,860
Then we mark it as buzz.

26
00:01:54,100 --> 00:01:56,260
Not sure why Autocomplete is not working.

27
00:01:59,100 --> 00:02:00,240
Otherwise.

28
00:02:01,160 --> 00:02:08,210
If that number modulus three equals zero and modulus five equals zero.

29
00:02:08,570 --> 00:02:14,540
So if the number being iterated through is a multiple of three and is a multiple of five, then we market

30
00:02:14,540 --> 00:02:16,160
as fest buzz.

31
00:02:24,020 --> 00:02:24,350
All right.

32
00:02:24,350 --> 00:02:24,990
I think we're good.

33
00:02:25,010 --> 00:02:29,630
I'm going to put a breakpoint right here, and let's see if what we have currently works.

34
00:02:32,630 --> 00:02:34,850
So I is going to start at zero now.

35
00:02:34,850 --> 00:02:41,690
Zero divided by three is going to return a remainder of zero and zero divided by five is also going

36
00:02:41,690 --> 00:02:43,340
to return a remainder of zero.

37
00:02:43,340 --> 00:02:49,640
So while this meets the requirements for phase buzz, what's going to print instead is physx.

38
00:02:51,390 --> 00:02:58,480
Because the first condition gets satisfied and it marks our number zero as far as that is not good.

39
00:02:58,500 --> 00:03:00,210
You will remember, I'll learn the part.

40
00:03:00,210 --> 00:03:01,980
I left you with a hint.

41
00:03:02,220 --> 00:03:08,040
There are three conditions for fizz, buzz and fizz buzz, and you need to be careful about their order.

42
00:03:08,070 --> 00:03:13,230
If something is Physx buzz, it also satisfies the conditions for Physx and buzz.

43
00:03:13,230 --> 00:03:15,030
So the number is zero.

44
00:03:15,510 --> 00:03:22,680
It satisfied the conditions for Physx buzz, but it also satisfies the condition for Physx because this

45
00:03:22,680 --> 00:03:25,350
executed first it marked it as physx.

46
00:03:25,380 --> 00:03:33,120
So what we need to do is make sure that the requirements for Physx buzz take precedence over the others.

47
00:03:34,080 --> 00:03:40,080
So first we check if something meets the requirements for MBAs.

48
00:03:40,170 --> 00:03:44,640
If it doesn't, then we check if it's fizz or buzz.

49
00:03:45,500 --> 00:03:46,480
No Right.

50
00:03:46,490 --> 00:03:50,630
And that was basically the entire trick behind this workbook.

51
00:03:53,640 --> 00:03:59,640
So zero divided by three returns a remainder of zero divided by five returns a remainder of zero.

52
00:03:59,640 --> 00:04:01,650
So it is marked as sbas.

53
00:04:01,650 --> 00:04:03,090
That is perfect.

54
00:04:03,090 --> 00:04:04,650
Let me put some space.

55
00:04:06,370 --> 00:04:07,980
Are we doing that?

56
00:04:09,920 --> 00:04:17,180
All right, now I equals one after we increment it, one divided by three does not return a remainder

57
00:04:17,180 --> 00:04:21,800
of zero, nor does it return a remainder of zero if divided by five.

58
00:04:21,800 --> 00:04:23,660
So it's not fizz buzz.

59
00:04:23,660 --> 00:04:24,770
It's not fizz.

60
00:04:24,770 --> 00:04:26,120
It's not buzz either.

61
00:04:26,120 --> 00:04:27,650
So it gets skipped.

62
00:04:27,680 --> 00:04:29,690
Same thing goes for number two.

63
00:04:31,100 --> 00:04:36,740
Now the number three divided by three does return a remainder of zero, but it does not satisfy this

64
00:04:36,740 --> 00:04:37,580
requirement.

65
00:04:37,580 --> 00:04:42,380
So this whole thing returns false, but it does satisfy this requirement.

66
00:04:42,380 --> 00:04:44,450
So three gets marked as fiz.

67
00:04:44,450 --> 00:04:45,740
That is perfect.

68
00:04:47,820 --> 00:04:48,710
The number four.

69
00:04:48,720 --> 00:04:50,130
Again, nothing.

70
00:04:50,400 --> 00:04:54,360
The number five does meet this requirement, not this one.

71
00:04:54,360 --> 00:04:57,920
So this gets evaluated to false does not run.

72
00:04:57,930 --> 00:04:59,910
This will also be false.

73
00:05:00,420 --> 00:05:03,960
Five divided by five does return a remainder of zero.

74
00:05:03,960 --> 00:05:06,450
So this gets marked as buzz.

75
00:05:06,840 --> 00:05:14,190
And if I just press continue to resume execution, naturally there are no other breakpoints, so the

76
00:05:14,190 --> 00:05:15,750
whole thing completes.

77
00:05:15,840 --> 00:05:23,580
Let's see if what we have matches what's honoring the part 0356 phase Buzz phase, Buzz, fist phase.

78
00:05:25,750 --> 00:05:28,570
And that is exactly what we have in our terminal.

79
00:05:28,570 --> 00:05:29,700
That is perfect.

80
00:05:29,710 --> 00:05:32,740
I hope you enjoyed this breakpoint session.
