So, when decoding, How will I differentiate btw a 5 and a small case s or a b and 6?

I have thot abt that. I have thot abt that. But the 196 character reduction was not enof. I needed to reduce it further. I thot abt re-encoding to a 16bit instead of a 8-bit, but that looks too ambigous.

I will keep working around it. Even if I can get a 50% reduction, I could manage and make do with it.

Actually, I looking at doing this so that I can help compress large numbers and re-encode for easy transmission. Note, I dont want any added zipping. I just want a raw data compressed. Or may be I really dont get the zippin concept cos, i am lookin at mobile phones who had to send sms and must be less than 160 xter.

4(2) - 3y = 11
8 - 3y = 11
3y= 3
y=1

now what?? how do I prove??

y = -1

.... pls note

So to be realistic, what is the least possible number that I can use to store a 800 (character range btw 0-9) character data and still be able to retain the order?

How about the least possible number for a 256 charactered data but with characters ranging btw [A-Z][a-z][0-9]?

Let me tell you my prob....

I have a 256 character data with the of [A-Za-z0-9] possibilities. I want to encode it. What is the barest minimum (length-wise) I can encode this data without losing the order in whihc they are arranged and How will I encode em?

Thnx.

Now I get.

But how do I know the order the numbers are pre-arranged initially when I want to re-arrange them back?

Alright guys,

I ve made it simpler.

I av a string of 800 integers and I want to compress them to around 50 digits. Does anybody know how I can add them together and a way of expanding the compressed numbers to retrieve the original 800 integers.

Thnx

Yea, I knew abt the RLE Algorithm. However, wot I want is quite different.

I have encrypted a pwd, and I need to compress it. RLE only works with data wit consecutively repeated data.

My encrypted data are not usually consecutively repeated. Is there a way of may be, representing (encoding) data in a compressed format?

Hi guys,

Its really nice having this forum. I just googled and this came up. I ve always love maths.

I am having a prob and I ve got limited time.

I ned and algorithm to encode a 256 long encrypted msg into a 32 long msg. I need this so as to be able to transfer the data over a medium.

Any algothm that can help. EWven if its just an idea, I could develop on it.

Thnx
