Hi,

It had been awhile since I wrote any Factor code, so I was trying to 
solve the following problem from reddit's dailyprogrammer subreddit:
http://bit.ly/1OtP8Qj

The solution I came up with in Factor looks like this:
http://bit.ly/1PY8j98

I struggled quite a lot coming up with this. Mainly in keeping things in 
my head and figuring out what I needed to do to bring the stack in order 
for the operations I was attempting..

Coming from an iterative programming background (with a little bit of 
exposure to functional programming), I find it quite hard to formulate 
solutions in Factor. Can someone help me with tips on how they approach 
writing code in Factor? What is your though process to turn a given 
pseudo code into a factor program?

For example, my pseudo code for the main portion of this problem (the 
find-match function) was as follows:

let buff = ""
let match = (indx=0, length=-1)
for each char c in input:
        find count(c) in buff
        if count == 2
                append c to buff
                check if str(first c to end) is longest and update match
                remove chars in buff before second c occurrence
        else if count == 1
                append c to buff
                check if str(first c to end) is longest and update match
                remove chars in buff before first c occurrence
        else
                append c to buff
discard buff and return match

Any pointers is greatly appreciated.

Thanks,
Sankar
