Need Help With Some Basic Computer Science Knowledge

"If the law is on your side pound on the law; if the facts are on your side pound on the facts; if neither is on your side pound on the table."

God, i need to compress this tongue twister by making up a dictionary: one "replacement phrase" per line; each line starts with a unique number followed by a decimal point; use an underscore to indicate a space. THen i need to type da encoded text!!:confused: da prof didnt say anything about dat...n i'm totally lost!!!

any one can help me out???
i'll appriciate it!

sorry, this is in the automotive forum because...?

Apart agreeing with Cray, this seems like a simple enough question. From your explanation, surely this is all you need:

Step one - lay out the problem:

1.If_the_law_is_on_your_side_pound_on_the_law;
2.if_the_facts_are_on_your_side_pound_on_the_facts ;
3.if_neither_is_on_your_side_pound_on_the_table

Step two - create code (define variables):

A=if
B=the
C=is
D=on
E=your
F=side
G=pound
H=law
I=facts
J=neither
K=table
L=are

Step three - substitution:

1.A_B_H_C_D_E_F_G_D_B_H;
2.A_B_I_L_D_E_F_G_D_B_I;
3.A_J_C_D_E_F_G_D_B_K

Please note that I did that manually so it's probably got errors, and I don't even know if it's what you're after. Plus I haven't done CS for about four years.

sorry guys..i confess dat i messed it up:( partly because i dont really know how da forums work here~ n partly because i get pissed by da assignment~....i'm sorry..

but, thanx anyways~

btw..i did think of da way u did, but it seemed to be too simple to accept~~ i dont know..i'm just being weird..sorry guys

Why is it too simple? It compresses the phrase correctly... the only thing is that I may have misunderstood your initial post, so that instead of prefixing the parts of the phrase itself with numbers, the variables should be prefixed with numbers. So
1.A=if
2.B=the
etc etc

Something along those lines, anyway.

There is no more effective way to compress plain text than the way I gave you, unless you want to create a single mathematical equation to represent it (and I'm not about to try that). The way I gave you is 1 byte per word in ASCII (assuming that ASCII uses 8 bits per character, if I remember rightly), whereas the original is between 2 and 40 bytes per word.

You can makle a better dictionary. Such as the following

1._the
2.if
3._on_your_side_pound_on
4._is
5._law
6._facts
7._neither
8._table
9._are

2154315;2169316;274318

Jaz,

You can get rid of most of your underscores by setting the dictionary to include the underscores,
so 1 == if_ and so on.

[Jaz]

heh. I realised that and was editing while you posted

[svvampy]

Heh, still didn't fix makle.

[ppuchi]

hmmm

how about dis?

1. if_
2. the_
3. law_
4. is_
5. on_your_side_pound_on_
6. facts_

¡°1234523;_126are_526;_1neither_452table.¡±

God is on my side and he will bring zgeek down.

P.S. This is a very interesting problem.

1234523;_126are_526;_1neither_452table.

takes up less space, but thats if you are allowed to mix dictionary terms with uncompresses data.
