Python | Permutation of a given string using inbuilt function
A permutation, also called an “arrangement number” or “order”, is a rearrangement of the elements of an ordered list S into a one-to-one correspondence with S itself. A string of length n has n! permutation. Examples:
Input : str = 'ABC' Output : ABC ACB BAC BCA CAB CBA
ABC ACB BAC BCA CAB CBA
Permutation and Combination in Python Permutations of a given string with repeating characters The idea is to use dictionary to avoid printing duplicates.

Time Complexity: O(n!) where n is the size of the string.
Auxiliary Space: O(n!)
