File Structure: Representation of data into secondary or auxiliary memory say any device such as hard disk or pen drives that stores data which remains intact until manually deleted is known as a f...Storage Structure: In this type, data is stored in the main memory i.e RAM, and is deleted once the function that uses this data gets completely executed.The difference is that storage structure has data stored in the memory of the computer system, whereas file structure has the data stored in the auxiliary memory.If the elements of a data structure result in a sequence or a linear list then it is called a linear data structure. Whereas, traversal of nodes happens in a non-linear fashion in non-linear data s...Lists, stacks, and queues are examples of linear data structures whereas graphs and trees are the examples of non-linear data structures.Arrays are the collection of similar types of data stored at contiguousmemory locations.It is the simplest data structure where the data element can be accessed randomly just by using its index number.Multi-dimensional arrays are those data structures that span across more than one dimension.This indicates that there will be more than one index variable for every point of storage. This type of data structure is primarily used in cases where data cannot be represented or stored using on...A linked list is a data structure that has sequence of nodes where every node is connected to the next node by means of a reference pointer. The elements are not stored in adjacentmemory locations. They are linked using pointers to form a chain. This forms a chain-like link for data storage. 1. Each node element has two parts: 2. The first node in ...
Linked lists can be considered both linear and non-linear data structures. This depends upon the application that they are used for. 1. When linked list is used for access strategies, it is considered as a linear data-structure. When they are used for data storage, it can be considered as a non-linear data structure.
Insertion and DeletionDynamic Data StructureNo wastage of memoryFollowing are the scenarios where we use linked list over array:Below are the cases where we use arrays over the linked list:To summarize, requirements of space, time, and ease of implementation are considered while deciding which data structure has to be used over what.This is a complex type of a linked list wherein a node has two references:This structure allows traversal of the data elements in both directions (left to right and vice versa).Applications of DLL are:Stack is a linear data structure that follows LIFO (Last In First Out) approach for accessing elements.Push, pop, and top (or peek) are the basic operations of a stack.Following are some of the applications of a stack:Jun 15, 2024 · In this Top 100 DSA interview questions, we have segregated the problems based on the Data structure or algorithm used to solve them.
