suppose you have a list of words and you want to unambiguously identify
each word in the list with the shortest number of characters.
for instance a list like : kill, kiss, take
i would want to get take just by typing t.
but you would have to type kil or kis to get kill or kiss.
where should i start googling? is this a matter of sorting?
i was thinking of trees for some reason.
