A program to take in a large number and output a smaller number

[godonga]

Hi
This question may sound wierd but I really need you help. I need to come up with a program that takes in at least a 16 digit number and outputs say a 6 digit number. I should be able to do the reverse as well i.e. put in the 6 digit number and output the exact 16 digit number.

Any ideas?

What permutation will you use to convert the 16-digit number to a six-digit number, and vice versa?

Indeed... Base 16 (Hex) will only let you squeeze in 8 [Base 10] digits... so you'd need a different algorithm. Perhaps Base 64 or something that is well documented or may already have library functions written.

I'm sure Google will help turn up algorithms.

Hope this helps,

Dan
