1 00:00:00,480 --> 00:00:01,620 Okay, hopefully, 2 00:00:01,620 --> 00:00:06,620 you managed to complete at least point 1 and point 2. 3 00:00:06,630 --> 00:00:09,840 And so let's start by solving these two. 4 00:00:09,840 --> 00:00:14,760 So number one is calculating the average of both teams. 5 00:00:14,760 --> 00:00:17,673 So let's create one variable for each. 6 00:00:19,647 --> 00:00:23,400 So scoreDolphins, and so to calculate the average, 7 00:00:23,400 --> 00:00:25,620 we simply add up all the three scores 8 00:00:25,620 --> 00:00:27,480 and then divide it by a three. 9 00:00:27,480 --> 00:00:29,763 So we already did something similar before. 10 00:00:30,690 --> 00:00:35,690 So that's 96 + 108 + 89, 11 00:00:37,170 --> 00:00:39,330 and then divide it by 3. 12 00:00:39,330 --> 00:00:41,010 And we need these parenthesis 13 00:00:41,010 --> 00:00:44,760 so that these plus operations are executed first, 14 00:00:44,760 --> 00:00:47,910 because the grouping, so the parenthesis, 15 00:00:47,910 --> 00:00:49,593 have a higher precedence. 16 00:00:50,460 --> 00:00:55,460 Okay, scoreKoalas is 88 + 91 + 110, 17 00:01:00,540 --> 00:01:02,313 and again, divide it by 3. 18 00:01:03,840 --> 00:01:07,833 And now let's quickly log both to the console here, 19 00:01:09,150 --> 00:01:12,063 scoreDolphins and scoreKoalas. 20 00:01:17,568 --> 00:01:19,500 Okay, so they're pretty close, 21 00:01:19,500 --> 00:01:23,670 but the dolphins have a little bit higher of an average. 22 00:01:23,670 --> 00:01:27,420 And so that's what we're working on in point 2, 23 00:01:27,420 --> 00:01:31,500 where we're gonna compare the average of both teams. 24 00:01:31,500 --> 00:01:36,420 So we are gonna use an 'if' statement 25 00:01:37,290 --> 00:01:38,793 or 'if else' probably. 26 00:01:39,840 --> 00:01:43,773 So scoreDolphins, if it's greater than scoreKoalas, 27 00:01:48,000 --> 00:01:52,180 then log to the console 'Dolphins win the trophy.' 28 00:01:56,610 --> 00:01:59,193 And we can get fancy here with some emoji. 29 00:02:01,500 --> 00:02:03,150 Let's see if we got one up, 30 00:02:03,150 --> 00:02:05,220 that's the one I'm looking for. 31 00:02:05,220 --> 00:02:07,020 But of course, once more, 32 00:02:07,020 --> 00:02:09,872 you don't need to worry about this part. 33 00:02:10,740 --> 00:02:12,753 Let's just copy this for the next one. 34 00:02:13,770 --> 00:02:15,660 So 'else,' and actually, 35 00:02:15,660 --> 00:02:19,290 we're going to use an 'else if' because of the draw, 36 00:02:19,290 --> 00:02:21,453 but let's talk about that one later. 37 00:02:22,860 --> 00:02:27,860 So if the score of the koalas is greater than scoreDolphins, 38 00:02:28,440 --> 00:02:31,080 then we're gonna print the opposite 39 00:02:31,080 --> 00:02:34,113 so that koalas win the trophy. 40 00:02:34,980 --> 00:02:37,137 And finally, 'else if,' 41 00:02:39,076 --> 00:02:42,653 scoreDolphins is equal to scoreKoalas, 42 00:02:44,040 --> 00:02:49,040 then we can simply say that no one wins the trophy, 43 00:02:52,050 --> 00:02:57,003 or actually, both win the trophy. 44 00:02:59,970 --> 00:03:02,910 Okay, so let's test that. 45 00:03:02,910 --> 00:03:06,210 And indeed, we get that the dolphins win the trophy, 46 00:03:06,210 --> 00:03:10,590 and that's because, as we know, this value is greater. 47 00:03:10,590 --> 00:03:12,300 And so actually, this first condition here 48 00:03:12,300 --> 00:03:14,400 turns out to be true right away. 49 00:03:14,400 --> 00:03:17,283 And so this block of code here gets executed. 50 00:03:18,150 --> 00:03:19,770 Now, let's just quickly increase 51 00:03:19,770 --> 00:03:22,200 the score of the koalas here, 52 00:03:22,200 --> 00:03:27,200 let's say 100, just to see if the second part also works. 53 00:03:29,280 --> 00:03:32,850 And indeed, now the koalas win the trophy. 54 00:03:32,850 --> 00:03:34,623 Okay, but let's put it back here. 55 00:03:35,520 --> 00:03:40,230 And here you could have actually done it in another way. 56 00:03:40,230 --> 00:03:45,230 So you could have done scoreDolphins less than scoreKoalas. 57 00:03:45,930 --> 00:03:47,730 So, basically, write the same as here, 58 00:03:47,730 --> 00:03:51,660 but instead of the greater, you would've used the less than. 59 00:03:51,660 --> 00:03:53,340 So that's the exact same thing, 60 00:03:53,340 --> 00:03:56,280 and both are equally valid. 61 00:03:56,280 --> 00:03:57,930 Then here in the last part, 62 00:03:57,930 --> 00:04:01,350 actually, we wouldn't even have needed this part, 63 00:04:01,350 --> 00:04:05,010 so that the score of dolphins is equal to score of koalas, 64 00:04:05,010 --> 00:04:08,040 because that's actually the only scenario that's left 65 00:04:08,040 --> 00:04:10,263 given these previous two conditions. 66 00:04:11,160 --> 00:04:14,070 So basically, if none of these here were true, 67 00:04:14,070 --> 00:04:15,660 really the only thing possible 68 00:04:15,660 --> 00:04:17,579 would be that they had the same score. 69 00:04:17,579 --> 00:04:21,630 And so a simple 'else' block would've been enough here. 70 00:04:21,630 --> 00:04:24,300 But anyway, this works just fine too. 71 00:04:24,300 --> 00:04:28,470 And so, again, what matters is that you made it work 72 00:04:28,470 --> 00:04:30,720 even if you did some things differently. 73 00:04:30,720 --> 00:04:33,000 For example, you could have stored the conditions 74 00:04:33,000 --> 00:04:35,310 in separate bullion variables, 75 00:04:35,310 --> 00:04:38,280 or you could have structured the 'if else' statement 76 00:04:38,280 --> 00:04:39,720 in some different way. 77 00:04:39,720 --> 00:04:42,090 But if you got the same result that we just saw here, 78 00:04:42,090 --> 00:04:43,680 then congratulations, 79 00:04:43,680 --> 00:04:46,743 that's a great work, well done, really. 80 00:04:48,439 --> 00:04:52,500 So maybe you even made it to Bonus number 1 and 2. 81 00:04:52,500 --> 00:04:56,100 And so let me solve them here now as well. 82 00:04:56,100 --> 00:04:59,613 So let's start by calculating the average. 83 00:05:05,280 --> 00:05:07,383 So this is gonna be Bonus 1, 84 00:05:09,067 --> 00:05:12,063 and yeah, let's copy this one too, 85 00:05:13,410 --> 00:05:16,500 let's copy this one, let's copy this one, 86 00:05:16,500 --> 00:05:18,750 so should have done it all in one go, 87 00:05:18,750 --> 00:05:21,933 so that we can now comment out this first part. 88 00:05:24,947 --> 00:05:28,980 So for test number 1, this should be 97. 89 00:05:28,980 --> 00:05:33,007 Then the second one should be 112 and 101. 90 00:05:35,010 --> 00:05:36,780 And for the koalas, 91 00:05:36,780 --> 00:05:41,463 we have 109, 95, and 123. 92 00:05:47,040 --> 00:05:48,990 Let's just quickly test. 93 00:05:48,990 --> 00:05:51,870 And so right now, the koalas win the trophy. 94 00:05:51,870 --> 00:05:54,060 So for now, everything works the same, 95 00:05:54,060 --> 00:05:57,870 but now we need to include this important condition here, 96 00:05:57,870 --> 00:06:00,270 which is that, with this rule, 97 00:06:00,270 --> 00:06:02,670 a team only wins if it has a higher score 98 00:06:02,670 --> 00:06:05,070 than the other team, which we already have, 99 00:06:05,070 --> 00:06:08,763 and at the same time, a score of at least 100 points. 100 00:06:10,140 --> 00:06:12,273 Okay, easy enough. 101 00:06:13,560 --> 00:06:17,670 So in this case, the dolphins win, okay? 102 00:06:17,670 --> 00:06:19,710 But now we also need to ensure 103 00:06:19,710 --> 00:06:23,040 that the dolphins have a score higher or equal 100. 104 00:06:23,040 --> 00:06:24,543 So let's just say that. 105 00:06:26,520 --> 00:06:29,730 So dolphins need to have a higher score than koalas, 106 00:06:29,730 --> 00:06:34,730 and scoreDolphins need to be greater or equal 100, 107 00:06:36,720 --> 00:06:40,770 and that's it, that's all we need for this requirement. 108 00:06:40,770 --> 00:06:43,140 And then the same thing here. 109 00:06:43,140 --> 00:06:46,170 So this is the scenario where the koalas win. 110 00:06:46,170 --> 00:06:47,760 So for the koalas to win, 111 00:06:47,760 --> 00:06:50,790 they need to have a higher score than the dolphins, 112 00:06:50,790 --> 00:06:55,790 and at the same time, they need to have at least 100 points, 113 00:06:56,160 --> 00:07:00,930 so just like before, greater or equal 100. 114 00:07:00,930 --> 00:07:03,990 And so once more, we used a logical operator here 115 00:07:03,990 --> 00:07:07,253 to model this situation essentially, okay? 116 00:07:09,390 --> 00:07:11,100 And actually, I think, with this, 117 00:07:11,100 --> 00:07:15,363 we implemented this bonus number 1. 118 00:07:17,334 --> 00:07:19,080 So let's try that again. 119 00:07:19,080 --> 00:07:21,080 And right now, of course, it still works 120 00:07:21,960 --> 00:07:25,740 because both have a score higher than 100. 121 00:07:25,740 --> 00:07:27,600 But let's change that now here, 122 00:07:27,600 --> 00:07:32,600 according to test data 2, to 106, so 106, 123 00:07:36,960 --> 00:07:39,660 and now they both win the trophy. 124 00:07:39,660 --> 00:07:44,660 So let's actually decrease all of these points by 20. 125 00:07:45,900 --> 00:07:50,283 So let's make it 81 and 86. 126 00:07:51,210 --> 00:07:55,140 So the average should still be the same now, yeah, 127 00:07:55,140 --> 00:07:57,420 but they're both below 100 now. 128 00:07:57,420 --> 00:08:01,140 And so this brings us to bonus number 2 129 00:08:01,140 --> 00:08:02,700 that says that the minimum score 130 00:08:02,700 --> 00:08:05,040 should also apply to a draw. 131 00:08:05,040 --> 00:08:09,420 So a draw only happens when both teams have the same score 132 00:08:09,420 --> 00:08:14,160 and both a score greater or equal 100 points, okay? 133 00:08:14,160 --> 00:08:16,470 And otherwise, no team wins the trophy, 134 00:08:16,470 --> 00:08:17,670 so that's important too. 135 00:08:19,320 --> 00:08:21,990 So let's translate that. 136 00:08:21,990 --> 00:08:24,600 So to be a draw, the score needs to be the same, 137 00:08:24,600 --> 00:08:26,010 which we already have, 138 00:08:26,010 --> 00:08:31,010 and the score of dolphins 139 00:08:31,080 --> 00:08:33,753 needs to be greater or equal 100, 140 00:08:34,620 --> 00:08:39,000 and the score of koalas 141 00:08:39,000 --> 00:08:42,953 needs to be greater, equal 100, okay? 142 00:08:45,502 --> 00:08:50,502 And else, well, then we can say that no one wins the trophy. 143 00:08:58,590 --> 00:09:03,590 And let's just add some sad emoji here. (chuckling) 144 00:09:05,838 --> 00:09:08,550 Okay, let's try that. 145 00:09:08,550 --> 00:09:13,110 And now we get that no one wins the trophy, okay? 146 00:09:13,110 --> 00:09:17,520 So that's because their scores are now below 100. 147 00:09:17,520 --> 00:09:21,600 And so we actually enter this last case here. 148 00:09:21,600 --> 00:09:24,660 But if we go back to the averages that we had before, 149 00:09:24,660 --> 00:09:29,660 so 106 and 101, let's see, 150 00:09:30,840 --> 00:09:32,790 and now both win the trophy 151 00:09:32,790 --> 00:09:35,310 because they have the same amount of points 152 00:09:35,310 --> 00:09:39,780 and they both have a number of points above 100. 153 00:09:39,780 --> 00:09:42,120 And so that's exactly what we have here. 154 00:09:42,120 --> 00:09:47,120 So same points, dolphins have over or at least 100 points 155 00:09:47,880 --> 00:09:50,700 and koalas have at least 100 points. 156 00:09:50,700 --> 00:09:53,253 And so in this case, both win the trophy. 157 00:09:54,960 --> 00:09:57,010 Finally, let's also test the scenario 158 00:09:58,080 --> 00:10:00,480 in which both have below, 159 00:10:00,480 --> 00:10:03,720 but the dolphins have a little bit more. 160 00:10:03,720 --> 00:10:05,283 Let's put this one here at 80. 161 00:10:06,330 --> 00:10:11,330 And so, now we see that the dolphins have 96 points 162 00:10:11,700 --> 00:10:15,330 and the koalas have 84, but still, no one wins the trophy. 163 00:10:15,330 --> 00:10:19,980 And that's because the dolphins have more than the koalas. 164 00:10:19,980 --> 00:10:22,650 So this part of the requirement is true, 165 00:10:22,650 --> 00:10:25,890 but they do not have over 100. 166 00:10:25,890 --> 00:10:28,620 So this part here is false, okay? 167 00:10:28,620 --> 00:10:32,250 And so true, this first part here is true, 168 00:10:32,250 --> 00:10:33,600 and the second part is false, 169 00:10:33,600 --> 00:10:36,180 and true and false gives false. 170 00:10:36,180 --> 00:10:38,730 And so then, all of these are skipped 171 00:10:38,730 --> 00:10:41,073 because they're also, obviously, false. 172 00:10:42,999 --> 00:10:45,990 And so we go straight to this last block, 173 00:10:45,990 --> 00:10:47,610 and so no one wins the trophy, 174 00:10:47,610 --> 00:10:50,610 which is exactly what we were expecting 175 00:10:50,610 --> 00:10:53,310 as a result here, okay? 176 00:10:53,310 --> 00:10:55,260 Now, if you didn't manage to do this here, 177 00:10:55,260 --> 00:10:57,480 again, don't worry, because I know 178 00:10:57,480 --> 00:10:59,700 that this is a little bit complicated already. 179 00:10:59,700 --> 00:11:01,830 And so, in case you managed 180 00:11:01,830 --> 00:11:04,350 to successfully complete this challenge, 181 00:11:04,350 --> 00:11:08,580 then a huge congratulations to you, well done. 182 00:11:08,580 --> 00:11:10,200 But if, for some reason, 183 00:11:10,200 --> 00:11:12,750 you were not able to complete the challenge, 184 00:11:12,750 --> 00:11:15,690 then don't worry all too much about it. 185 00:11:15,690 --> 00:11:18,030 You can always go back to the lectures 186 00:11:18,030 --> 00:11:20,940 where we first learned about these topics. 187 00:11:20,940 --> 00:11:23,580 And you can, of course, after this video, 188 00:11:23,580 --> 00:11:26,280 also review the code a little bit more carefully 189 00:11:26,280 --> 00:11:29,610 to make sure 100% that you understand, 190 00:11:29,610 --> 00:11:34,260 especially this last example that we just worked on, okay? 191 00:11:34,260 --> 00:11:37,560 But anyway, great job in completing this challenge, 192 00:11:37,560 --> 00:11:40,323 and now I see you in the next video.
