00:00:01,310 --> 00:00:06,320
So we'll come back at the end of the section you have four assignments that you have to do.

2
00:00:06,320 --> 00:00:12,080
This is the first one of doors and in each of the assignments I try to embed some of the things that

3
00:00:12,080 --> 00:00:15,190
we learned throughout this section in this one.

4
00:00:15,190 --> 00:00:22,550
You receive a sequence of words that is in a long string and you have to break it into a specific waltz

5
00:00:22,570 --> 00:00:28,250
you have to find a method or a function that can break this thing into words and then you have to find

6
00:00:28,370 --> 00:00:34,850
the unique forms and you have to count them up to find out how many unique words are in that string.

7
00:00:34,850 --> 00:00:39,390
Let me show you the beginning part of the job and then you have to do the rest of it.

8
00:00:39,400 --> 00:00:49,400
So when I go to execute and when I close this start a new application command line or is called is unique

9
00:00:49,840 --> 00:00:59,550
worts and in the only words you have to add the file that you received with this particular video.

10
00:00:59,760 --> 00:01:04,200
So this is that one side that there is a long string.

11
00:01:04,250 --> 00:01:08,190
So I'm going to copy that and go back to school.

12
00:01:08,270 --> 00:01:13,960
I'm going to clean everything up as usual because that's how I like it to be.

13
00:01:14,010 --> 00:01:21,850
Here is our very long and it's a string which is essentially the first two paragraphs of the week GPDA

14
00:01:21,880 --> 00:01:23,220
about Objective-C.

15
00:01:23,430 --> 00:01:32,060
So your goal is to break this into single word so Objective-C is a general purpose.

16
00:01:32,100 --> 00:01:38,370
So on and so forth we can pick them into a single word add them all into an array and then count up

17
00:01:38,370 --> 00:01:46,680
the unique words and find out how many unique words are in this are a string of what or sequence of

18
00:01:46,680 --> 00:01:47,180
words.

19
00:01:47,370 --> 00:01:53,490
So good luck once you are done please submit your solution in the forum so the others can benefit from.

20
00:01:53,680 --> 00:01:57,330
And if you're trying to into a serious difficulty let me know.

21
00:01:57,360 --> 00:01:57,990
I've tried.
