I have written a program, in which it will ask the user to enter a string of length exactly 9. I have got a dictionary file with me which contains over two hundred thousand words. My job is to output all the possible words between lengths 4 to 9 that can be formed. For example:-

If the input word / string is LARBITNLI, then the output should be TILL, TRILL and BRILLIANT. I have written the program but I think it is most inefficient program ever because it is taking too much time to finish. I never actually allowed to finish but since I put several print statements, I could see that it is printing out the correct possible words.

Current Algorithm

I am taking the first word of dictionary (for example:- APPLE) and then I am checking if the frequency of all 27 alphabets in APPLE is than or equal to the frequency of all 27 alphabets in LARBITNLI.

Is there any better algorithm out there ? ( definitely :-) )
