9/9/2023 0 Comments String permutation![]() ![]() The first line of each test file contains a single integer n, the length of the string array s.Įach of the next n lines contains a string s. We only print the three visibly unique permutations: ![]() In this case, there are three matching pairs of permutations where s = ab and s = ab are switched. In other words, if s = s, then print either s s or s s but not both.Ī three element array having three distinct elements has six permutations as shown above. Only one instance of a permutation where all elements match should be printed. Note: There may be two or more of the same string as elements of s.įor example, s =. The six permutations in correct order are: ab bc cd See the ‘note’ below for an example.Ĭomplete the function next_permutation which generates the permutations in the described order.įor example, s =. If two permutations look the same, only print one of them. Given an array of strings sorted in lexicographical order, print all of its permutations in strict lexicographical order. If one string is an exact prefix of the other it is lexicographically smaller, e.g., gh >ghij. That means they are ordered by comparing their leftmost different characters. Strings are usually ordered in lexicographical order.
