Aug 26, 2020 · Dynamic Array is simply growable array. A data structure that automatically grows when elements are added into it. Create a list, seqList, of N empty sequences, where each sequence is indexed...

INTEGER n * 2. 2D_INTEGER_ARRAY queries */ public static List<Integer> dynamicArray (int n, List<List<Integer>> queries) { // Write your code here List<List<Integer>> seqList = new ArrayList<List<Integer>> (n); for (int i =0; i<n; i++) { seqList.add (new ArrayList<> ()); } Integer lastAnswer = 0; List <Integer> result = new ArrayList<...

Dec 29, 2020 · In this article, we are going to see the solution for dynamic array which part of problem solving section in HackerRank. Here two types of queries will be used that is functioned as below. Query: 1 x y. Find the sequence seq, , at index ((x ^ lastAnswer) % n) in seqList. Append integer y to sequence seq. Query: 2 x y

Oct 29, 2024 · Today, we’re tackling the “ Dynamic Array ” challenge, which introduces the concept of using multiple arrays within an array structure. This challenge is essential for building a foundational...

In this HackerRank in Data Structures - Dynamic Array. Declare a 2-dimensional array, arr, of n empty arrays. All arrays are zero indexed. Declare an integer, lastAnswer, and initialize it to 0. Declare an answers array. Parse through each query. The format of each query will be [type, x, y].
