Anagram finder

iamthwee 0 857 Views

Well technically it isn't an anagram finder, more of a word descrambler program.

It is useful for games like scrabble etc.

All you need is a dictionary file, which you can find readily online. Make sure the file has the words on each line and they are all in lowercase.

The program has a good time complexity because it doesn't brute force every permutation of the scrambled letters. That means it can descramble very long words in a short space of time (as long as they are in the dictionary file.)

Notes: Program is NOT thorougly tested, bugs may exist.

Samle output

Enter jumbled set of letters:
rats

***RESULT***

tsar
tars
star
rats
