Question

Write a recursive function to print all the permutations of a

string. For example, for the string abc, the printout is:
abc
acb
bac
bca
cab
cba
(Hint: Define the following two functions. The second function is a helper function.
def displayPermuation(s):
def displayPermuationHelper(s1, s2):

The first function simply invokes displayPermuation(" ", s). The second
function uses a loop to move a character from s2 to s1 and recursively invokes t with a new s1 and s2. The base case is that s2 is empty and prints s1 to the console.)
Write a test program that prompts the user to enter a string and displays all its permutations.
