Given a string S. The task is to print all unique permutations of the given string that may contain duplicates in lexicographically sorted order. Consider a rat placed at (0, 0) in a square matrix mat ...

Given two strings, s1 and s2, determine if s2 contains a permutation of s1. A permutation of s1 is a substring of s2 that contains the same characters with the same frequencies, but not necessarily in ...

In other words, one of the first string's permutations is the substring of the second string. * The idea behind this approach is that one string will be a permutation of another string * only if both ...

LeetCode problem: 567. Permutation in String. Given a pattern and a string, find out if the string contains any permutation of the pattern. Input: Pattern = "abc", String = "oidbcaf" Output: true ...

Abstract: In this paper, we introduce new codeword sets based on order complexity (OC) which measures uncertainty of the order having each permutation string. The proposed codeword sets are generated ...
