Use a stack to enumerate all permutations of a string. Suppose you want to find all permutations of the string meat. Push the string +meat on the stack.
While the stack is not empty
Pop off the top of the stack.
If that string ends in a + (such as tame+)
Remove the + and add the string to the list of permutations.
Else
Remove each letter in turn from the right of the +.
Insert it just before the +.
Push the resulting string on the stack.
For example, after popping e+mta, you push em+ta, et+ma, and ea+mt.

answei'm sorry. i am having trouble understanding what you're asking? i'm willing to but tell me what you mean : )

explanation:

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
