9/3/2023 0 Comments Permutation of string![]() More specifically, we'll be working with permutation in a String. In this tutorial, we'll learn how we can easily create permutations in Java using third-party libraries. In other words, it is all the possible variations of the collection order. O (1), s1FrequencyMap and s2FrequencyMap of size 26 is used. Introduction A permutation is the rearrangement of elements in a set. O(m+n), where n is the length of string s 1 and m is the length of string s 2 . S1FrequencyMap.put(ch,s1FrequencyMap.getOrDefault(ch,0)+1) įor( is1FrequencyMap,HashMaps2FrequencyMap) Complexity Analysis for Number of Closed Islands Leetcode Solution Time Complexity Example: Java program to get all the permutation of a string. That means we will be doing the steps while j s2 length For example, string ABC has permutations ABC, ACB, BAC, BCA, CAB, CBA.
