View Discussion Show Improve Article Save Article View Discussion Improve Article Save Article Write a python program to print all the permutations of a string in lexicographical order. Examples: Input : python Output : hnopty hnopyt hnotpy hnotyp hnoypt ...... ytpnho ytpnoh ytpohn ytponh Input : xyz Output : xyz xzy yxz yzx zxy zyx Method 1: Using the default library itertools function permutations. permutations function will create all the permutations of a given string and then we sort the result to get our desired output. Python
Output : abc acb bac bca cab cba Method 2:
Python3
Output : abcd abdc acbd acdb adbc adcb bacd badc bcad bcda bdac bdca cabd cadb cbad cbda cdab cdba dabc dacb dbac dbca dcab dcba Time Complexity: O(n*n!) How do you find all permutations of string without recursion?How do you print all permutations of a string in Python?Find all permutations of a string in Python. import itertools.. if __name__ == '__main__':. s = 'ABC'. nums = list(s). permutations = list(itertools. permutations(nums)). # Output: ['ABC', 'ACB', 'BAC', 'BCA', 'CAB', 'CBA']. print([''. join(permutation) for permutation in permutations]). How do you get all the possible combinations of a string in Python?To find all possible permutations of a given string, you can use the itertools module which has a useful method called permutations(iterable[, r]). This method return successive r length permutations of elements in the iterable as tuples.
How do you do permutations in Python without Itertools?A.
To create combinations without using itertools, iterate the list one by one and fix the first element of the list and make combinations with the remaining list. Similarly, iterate with all the list elements one by one by recursion of the remaining list.
