Block 3 Part 1 - Compression

Just completed sections 4.1 and 4.2 dealing with compression. I found this really interesting, and tackled the little activities with relish!

Here's my version of the simple compression of a poem extract (it's almost but not quite the same as the given solution):

Activity 26


Now try coding this short extract from a poem by Wendy Cope (1992) by suggesting a dictionary and then encoding the extract:


I am a poet.
I am very fond of bananas.
I am bananas.
I am very fond of a poet.
I am a poet of bananas.
I am very fond.

(a)   Build up a dictionary:

Code
Word(s)
1
I am
2
a poet
3
very fond
4
bananas
5
of

(b)  Encode the poem extract:

1 2.
1 3 5 4.
1 4.
1 3 5 2.
1 2 5 4.
1 3.
