hello,
the problem question is :-
1) there is a file given in which words are stored
2)we have to make T9 dictionary that's available in our cellphones
User can input for example 223 so the output should be every meaningful word that comes from this combination like bad,ace etc..
(223 means similar to our cellphones where 2=abc 3=def 4=ghi..)
Just give me few logics then i will try to make it but i am not getting a general idea i want somebody to give me general idea only!
i know we need permutations in this program but how??Please explain me in better way
