These are the user uploaded subtitles that are being translated: 1 00:00:00,990 --> 00:00:04,580 All right, what is going on, ladies and gentlemen, my name is Vlad. 2 00:00:04,620 --> 00:00:11,310 This is Alpha Tech Academy and we are proceeding with additional exercises in our programming course. 3 00:00:12,030 --> 00:00:19,290 So this video and this exercise, what we are going what you are basically required to do is to write 4 00:00:19,290 --> 00:00:24,330 a function that gets some number of an integer type and a digit. 5 00:00:25,320 --> 00:00:30,760 OK, and these function that you are going to write has to do two things, OK? 6 00:00:31,170 --> 00:00:32,180 The function should. 7 00:00:32,580 --> 00:00:36,360 So let's say the function should know. 8 00:00:36,360 --> 00:00:38,970 Let's specify what exactly each should do. 9 00:00:39,540 --> 00:00:41,190 One, two. 10 00:00:42,880 --> 00:00:49,790 So the function, first of all, should find out how many numbers, OK, how many? 11 00:00:49,810 --> 00:00:52,300 No, let's see how many digits. 12 00:00:52,670 --> 00:00:55,690 OK are less than the specified digit. 13 00:00:56,200 --> 00:01:03,880 So when we are given with this number, OK with this num value and this value can be of one digit to 14 00:01:03,880 --> 00:01:07,000 the five digits, seven digits and so on. 15 00:01:07,660 --> 00:01:15,310 And we are interested in finding out how many digits inside of these naoum value are basically less 16 00:01:15,310 --> 00:01:20,460 than these digits that was specified as the second argument for these function. 17 00:01:21,490 --> 00:01:25,120 So we will need to Lizzi print. 18 00:01:25,780 --> 00:01:38,950 OK, the total amount, total amount of digits in normal that are which are less than digits. 19 00:01:39,800 --> 00:01:41,700 OK, is that clear so far? 20 00:01:42,670 --> 00:01:46,780 And also what will will have to do is to return. 21 00:01:46,810 --> 00:01:55,690 OK, we are going once again to discuss the differences between these two formulations or I don't know, 22 00:01:55,690 --> 00:01:57,730 terminologies, whatever you call it. 23 00:01:58,420 --> 00:02:04,720 The function should return the average the average of those digits. 24 00:02:04,870 --> 00:02:12,340 OK, the average of the values of these digits that are that are less than digits. 25 00:02:13,180 --> 00:02:16,810 OK, so let's see a couple of examples. 26 00:02:16,820 --> 00:02:20,740 Let's say that we have, I don't know, example number one. 27 00:02:21,220 --> 00:02:25,120 And then we have example number two. 28 00:02:25,510 --> 00:02:30,760 So at example number one, what we have is something like this, I don't know, let's say we have a 29 00:02:30,760 --> 00:02:39,040 number like one three, five and seven, OK, and one three five seven two. 30 00:02:39,490 --> 00:02:42,770 That's the number that what number equals two. 31 00:02:42,790 --> 00:02:47,220 So now equals to this one and digit equals two. 32 00:02:47,230 --> 00:02:47,650 I don't know. 33 00:02:47,650 --> 00:02:49,100 Let's see three. 34 00:02:50,290 --> 00:02:57,670 And in this case we know that if we take a look, if we take a look at this number, we will see that 35 00:02:57,670 --> 00:02:59,310 one is less than three. 36 00:02:59,890 --> 00:03:03,660 Three is not less than three, five seven and two is less than three. 37 00:03:04,090 --> 00:03:08,060 So we know that one and two are less than these value three. 38 00:03:08,440 --> 00:03:10,300 So the function should print. 39 00:03:11,140 --> 00:03:17,830 It should print the amount of digits, the amount of digits, which are less than digits itself. 40 00:03:18,320 --> 00:03:24,280 Then in this case, we should print just two because we have two digits, less than three. 41 00:03:24,280 --> 00:03:32,810 And then the value of these three major and also what these function should do is to return the average. 42 00:03:33,130 --> 00:03:41,680 So if we know that one and two are basically the values that interest us, then in this case we should 43 00:03:41,680 --> 00:03:46,300 return one plus two divided by two. 44 00:03:46,480 --> 00:03:46,910 Right. 45 00:03:46,950 --> 00:03:49,350 That's basically what should what we should return. 46 00:03:49,750 --> 00:03:59,140 And in this case, it's going simply to be like to return turn one and a half. 47 00:03:59,780 --> 00:04:04,600 OK, so that's basically what this function is all going to do. 48 00:04:04,950 --> 00:04:06,930 If we take another example, I don't know. 49 00:04:06,940 --> 00:04:10,510 Nomikos to one, two, three, one, two, three. 50 00:04:10,900 --> 00:04:16,240 And digit equals digit equals to, I don't know, three once again. 51 00:04:16,540 --> 00:04:20,470 Then in this case, the function is going to print what he's going to print. 52 00:04:20,710 --> 00:04:28,120 One, two, one, two, four four is the total amount of digits, less than the digit three. 53 00:04:28,420 --> 00:04:34,390 And the function is going to return average and its average is going to be one plus two plus one plus 54 00:04:34,390 --> 00:04:36,190 two is six divided by four. 55 00:04:36,610 --> 00:04:38,760 In this case, that's just what happened. 56 00:04:39,010 --> 00:04:41,770 The function is also going to return one and a half. 57 00:04:44,140 --> 00:04:48,670 So I hope the instructions for this exercise are basically clear. 58 00:04:48,670 --> 00:04:56,380 Do you think about the signature of the of the function as well as one this function gets where it should 59 00:04:56,380 --> 00:05:00,020 it print the values we are or should it return? 60 00:05:00,040 --> 00:05:08,450 OK, make the distinguish and basically understand the differences between printing and returning something. 61 00:05:08,480 --> 00:05:12,550 OK, I think we talked about it pretty pretty much enough. 62 00:05:13,920 --> 00:05:17,310 So, yeah, so that's about these function. 63 00:05:18,360 --> 00:05:24,480 Try to do your best, guys, give it a try on your own, and of course, we'll solve this exercise together 64 00:05:24,900 --> 00:05:29,400 right away once you are done in our solutions. 65 00:05:30,000 --> 00:05:32,420 So if you have any questions, feel free to ask them. 66 00:05:32,460 --> 00:05:34,530 And until the solutions, I'll see you that. 6539
