0:00:00.000,0:00:02.000 Let us take a look again 0:00:02.000,0:00:04.000 at our remove html markup function. 0:00:04.000,0:00:08.000 Here I'm going back to the earlier version, 0:00:08.000,0:00:10.000 which is sort of fixed. 0:00:10.000,0:00:14.000 Now let's take a look at this condition up here. 0:00:14.000,0:00:16.000 We want to know where the core value 0:00:16.000,0:00:18.000 could possibly have come from 0:00:18.000,0:00:21.000 To do so, we follow the data dependencies. 0:00:21.000,0:00:23.000 What are the statements that this statement 0:00:23.000,0:00:25.000 is data dependent upon? 0:00:25.000,0:00:27.000 To do so, we will look at the places 0:00:27.000,0:00:29.000 where quote would be written. 0:00:29.000,0:00:32.000 And which also would be executed 0:00:32.000,0:00:35.000 before this statement will be executed. 0:00:35.000,0:00:38.000 For instance, this statement would be data 0:00:38.000,0:00:40.000 dependent on that earlier statement. 0:00:40.000,0:00:43.000 Because here quote is being written, 0:00:43.000,0:00:45.000 and here quote is being read. 0:00:45.000,0:00:48.000 Therefore, the statement A up here sets the state 0:00:48.000,0:00:51.000 that B later on keeps on processing. 0:00:51.000,0:00:54.000 If you want to understand how B behaves, 0:00:54.000,0:00:56.000 we follow the data dependencies to A 0:00:56.000,0:00:59.000 and find that this is one of the statements 0:00:59.000,0:01:01.000 that sets the state that B depends upon. 0:01:01.000,0:01:03.000 Now for a quiz. 0:01:03.000,0:01:07.000 Which are the other statements that B data depends upon? 0:01:07.000,0:01:09.000 Is this for C in S, 0:01:09.000,0:01:13.000 is this elf of C equals the greater sign and not quote, 0:01:13.000,0:01:15.000 is this quote equals not quote, 0:01:15.000,0:01:18.000 or is this out equals out plus C? 0:01:18.000,0:01:20.000 Check all that apply.
