To get All Possible Combination of word

Hi All ,

After Long Search on SDN , i am Posting this Thread ...

Can anyone tell me Any Function Module or Hint to get Possible Different Combination of Word .

Say Example i will pass one word 'deepak' .

i should get result

deepak

deepka

deekap

deekpa

and so on till 36 combination

.

It is not nessecary that i will pass only six charater word it can be any word of any length .

i know IT might look as i am doing this for testing .. But it will help me to create one Function Module which will return all possible combination .

regards

Deepak.
