Where categories are - -3 -00:00:05,630 --> 00:00:08,650 -characteristics of each input element. So - -4 -00:00:08,650 --> 00:00:11,490 -let me illustrate what that means using an example. And to do - -5 -00:00:11,490 --> 00:00:14,440 -that I'm going to use again the example of the split program, as - -6 -00:00:14,440 --> 00:00:16,830 -we are already familiar with it and we kind of already played - -7 -00:00:16,830 --> 00:00:20,110 -with it. When we were talking about the generic black box approach. - -8 -00:00:20,110 --> 00:00:22,293 -So let me bring back the program, and let me remind you - -9 -00:00:22,293 --> 00:00:25,440 -that what the program does is to take two inputs, a string and - -10 -00:00:25,440 --> 00:00:28,560 -the size, and it breaks down the string into chunks, - -11 -00:00:28,560 --> 00:00:31,300 -whose length is size. If we look at the split program - -12 -00:00:31,300 --> 00:00:34,330 -there are two input elements, str and size so we going to - -13 -00:00:34,330 --> 00:00:37,930 -identify categories for these two. So starting from str, what are - -14 -00:00:37,930 --> 00:00:41,228 -the interesting characteristics of the string? In, in this step - -15 -00:00:41,228 --> 00:00:44,948 -you're going to use your domain knowledge, your understanding of what a - -16 -00:00:44,948 --> 00:00:47,986 -string is, and for example we might identify the length of - -17 -00:00:47,986 --> 00:00:50,528 -the string and the content of the string as the two - -18 -00:00:50,528 --> 00:00:53,840 -main characteristics that we want to focus on. If we now - -19 -00:00:53,840 --> 00:00:57,540 -move our focus to size, the only characteristic I can really - -20 -00:00:57,540 --> 00:01:00,340 -think of for an integer is its value. So that's what - -21 -00:01:00,340 --> 00:01:02,470 -I'm going to mark here. So at the end of the step - -22 -00:01:02,470 --> 00:01:05,030 -what we have is that we have two categories. So two - -23 -00:01:05,030 --> 00:01:08,930 -interesting characteristics for the string input str, which are the length - -24 -00:01:08,930 --> 00:01:12,940 -and the content. And one category for the integer input size - -25 -00:01:12,940 --> 00:01:16,480 -which is its value. And notice that there's not only one solution. - -26 -00:01:16,480 --> 00:01:18,200 -So there's not only one possibility. - -27 -00:01:18,200 --> 00:01:20,384 -So that the specific characteristics that you - -28 -00:01:20,384 --> 00:01:22,800 -will identify are somehow subjective. But the - -29 -00:01:22,800 --> 00:01:25,630 -important point is that you identify characteristics - -30 -00:01:25,630 --> 00:01:29,259 -that are meaningful and they sort of cover the main aspects of the - -31 -00:01:29,259 --> 00:01:31,200 -inputs, which is the case for the - -32 -00:01:31,200 --> 00:01:33,440 -categories that we've identified in this example. |
