Print all permutations in sorted (lexicographic) order. For instance, the words ‘bat’ and ‘tab’ represents two distinct permutation (or arrangements) of a similar three letter word. I have a list like this: from itertools import permutations l = [1,1,1,1,1,1,1,2] The duplicate '1' entries in the original list mean that the distinct permutations only depend on where the '2' Use inbuilt push, pop functions in the single stack. Below is Java implementation of the approach. If you find my solutions hard to comprehend, give yourself a time to solve easier questions or check discussion section to problem on This is an example of permutation with repetition because the elements of the set are repeated and their order is important.
