Given a string, s, matching the regular expression [A-Za-z !,?._'@]+, split the string into tokens. We define a token to be one or more consecutive English alphabetic letters. Then, print the number of tokens, followed by each token on a new line. Sample Input : He is a very very good boy, isn't he? Sample Output In this tutorial, we will see how to find all permutations of a given string in alexicographically sorted manner with Python. Dictionary is an example of a group of words sorted in a lexicographical manner. For example: All the permutations of the word ‘ABC’ are: 1.ABC 2.BAC 3.CAB 4.ACB 5.BCA 6.CBA. Lexicographically sorted permutations are:
Aug 08, 2016 · Python implementation. Below is an in-place Python 3 implementation of the described algorithm. If you do not want mutability, wrap the algorithm calls with a function that copies the list. However, take into consideration that for very large lists this may use a significant amount of memory if you are interested in several permutations. Return the lexicographically smallest equivalent string of S by using the equivalency information from A and B. Example 1: Input: A = "parker", B = "morris", S = "parser" Output: "makkek" Explanation: Based on the equivalency information in A and B, we can group their characters as [m,p], [a,o], [k,r,s], [e,i]...
