Let me + +2 +00:00:03,320 --> 00:00:05,790 +rearrange things a little bit to make more room. So now I'm + +3 +00:00:05,790 --> 00:00:09,160 +going to put the domains for size and for strength one next to + +4 +00:00:09,160 --> 00:00:12,210 +the other. So let's look at what some possible inputs will be + +5 +00:00:12,210 --> 00:00:15,140 +for the sub domains that we identified when we use the idea + +6 +00:00:15,140 --> 00:00:17,790 +of selecting input of the boundary. If we look at the first + +7 +00:00:17,790 --> 00:00:21,860 +subdomain, size less than zero, one reasonable input is, size equals to + +8 +00:00:21,860 --> 00:00:25,360 +minus 1, because minus 1 is the boundary value for the domain + +9 +00:00:25,360 --> 00:00:28,530 +of the integers less than zero. If we look at the third + +10 +00:00:28,530 --> 00:00:32,119 +subdomain, possibly interesting case is the one of size of equal to + +11 +00:00:32,119 --> 00:00:34,900 +1, for the same reasoning that we used for the previous subdomain, + +12 +00:00:34,900 --> 00:00:37,670 +for size less than zero. And, let's try to select another one + +13 +00:00:37,670 --> 00:00:40,870 +for this subdomain, for the integers greater than zero. If there is + +14 +00:00:40,870 --> 00:00:44,200 +a concept of maximal integer, we can select that one as our + +15 +00:00:44,200 --> 00:00:47,140 +boundary value. And of course we could select much more, but this + +16 +00:00:47,140 --> 00:00:50,630 +is just to give you an idea. Other possible inputs. One interesting + +17 +00:00:50,630 --> 00:00:53,310 +example for the first one, string with length less than + +18 +00:00:53,310 --> 00:00:57,690 +size will be a string with length size minus one. Again + +19 +00:00:57,690 --> 00:01:00,240 +this is the boundary value for this domain. And we could + +20 +00:01:00,240 --> 00:01:03,500 +continue in this way like for example selecting a string who's + +21 +00:01:03,500 --> 00:01:07,310 +length is exactly size as a boundary value for this + +22 +00:01:07,310 --> 00:01:10,490 +other domain. Instant one, and we look back actually to this + +23 +00:01:10,490 --> 00:01:12,940 +example and look at it in a more extensive way when + +24 +00:01:12,940 --> 00:01:15,690 +we actually talk about a specific method for doing this kind + +25 +00:01:15,690 --> 00:01:16,340 +of process. -- cgit 1.4.1
