WEBVTT 00:00.240 --> 00:06.590 At this point it is important to separate the east at least in classical programming r.d. our structures 00:06.630 --> 00:11.310 that contains on Lou one type of dad for example integers and has a fixed size. 00:11.400 --> 00:17.520 So the example we sold previously is zanardi with size three in the to the numbers released on the other 00:17.520 --> 00:18.130 hand. 00:18.210 --> 00:19.940 Completely different properties. 00:20.010 --> 00:21.260 The core idea is the same. 00:21.270 --> 00:24.930 You can see from the items in the video but it works differently. 00:25.050 --> 00:28.280 First of all the number of hide them seem the least is not fixed. 00:28.290 --> 00:33.540 For example you can start at least with only one number and then the process of your program you can 00:33.540 --> 00:34.980 add the more and model numbers. 00:34.980 --> 00:40.660 This is possible because at least basically has a number and a pointer that points to the next number. 00:40.710 --> 00:43.800 So you have a list with the number 5 in you 1. 00:43.800 --> 00:45.090 Also the number 7. 00:45.090 --> 00:47.850 You can first save the 5 and then make the first one. 00:47.850 --> 00:48.990 Point to the second one. 00:48.990 --> 00:54.290 So the advantage is that you can point to as many items as you want in the same time they cite them 00:54.300 --> 00:59.700 skin by their numbers characters or anything that your program needs in the same least So a valid question 00:59.760 --> 01:01.520 is why did we use diaries. 01:01.520 --> 01:04.290 We can always use at least in the we are better. 01:04.290 --> 01:07.080 The problem is that we have a processing time difference. 01:07.120 --> 01:11.430 For example if you want to talk on Lissy fifth write them off and narey. 01:11.490 --> 01:16.410 The computer will find these ideas immediately in Gondar as with the least that needs to start from 01:16.410 --> 01:21.890 the first thight them then point to this second third and fourth and eventually reach the fifth. 01:21.930 --> 01:25.620 Especially if you go from Big least like out to a hundred thousand sides. 01:25.630 --> 01:27.980 Least you will have up a single dime problem. 01:27.990 --> 01:30.360 But this is not the problem that you need to worry about. 01:30.390 --> 01:34.480 Now you only need to know that in both on your watch and with the least. 01:34.530 --> 01:38.970 So you you include this specific size or at least then add or remove part of it. 01:38.970 --> 01:42.430 In addition you can find specific numbers inside the beliefs. 01:42.480 --> 01:44.940 For example if you have at least named A. 01:45.000 --> 01:47.350 You can write a deposes to. 01:47.380 --> 01:52.080 You will get to the third bar at least because it zeyda is the first one is a circle. 01:52.090 --> 01:53.250 In do is the third.
