We will use the sequence (0, 1, 2, 5, 3, 3, 0) as a running example. The key observation in this algorithm is that when we want to compute the next permutation, we must “increase” the sequence as little as possible.Just like when we count up using numbers, we try to modify the rightmost elements and leave the left side unchanged. Python’s itertools.permutations computes 10-element permutations in about a second and 11–element permutations in about 25 seconds on my (admittedly aging) computer. Find Permutation On the other hand, now your job is to find the lexicographically smallest permutation … The repository contains solutions to various problems on interviewbit.
