Linear Data Structure
A linear data structure is one in which the data elements are ordered in a linear fashion, with each member linked to its immediate predecessor and successor. There is only one tier in a linear data structure. This means that we only need to run once to go through all of the elements. Considering the linear organization of computer memory, linear data structures are simple to implement. The array, stack, queue, and linked list are just a few examples.
Attributes of Linear Data Structure
● There is a direct connection between each data element in the sequence and the next.
● Because the information is stored in a computer's memory in sequential order, implementing the linear structure of data is straightforward.
● The one-to-one connection between the data pieces recorded in the data structure is the single connection.
● Because the data items are all kept in a single level, traversal can be completed in a single pass.
● If a linear data storage structure is used, very little of the available computer memory will be put to use.
● The data structure's temporal complexity grows proportionally with its size.
Next, we understand in-depth the different linear data structures.
Various Linear Data Structures to Understand
Array
Contiguous memory spaces are used by arrays, a form of structure, to hold identical data items. The elements of the same kind are kept in order in an array. The fundamental principle behind arrays is that several items of the same type can be kept in one location. Specifying the size of an array is necessary before saving data to storage. All of the data is indexed so that you can easily find and change any specific value in the array.
One common use for arrays is to keep track of student's grades for the entire class. If there are twenty learners, the array size must be specified as twenty. If an array is formed, then individual grade variables are unnecessary. Instead, all students grades can be kept in the array. The elements of the array can be accessed through a straightforward traversal of the array's indices.
Linked list
When multiple objects need to be kept in sequential order, a linked list is the best choice. Each data object in the structure will have a copy of the information and a pointer to the next data object in the structure. There is a reference to nothing at the very end of the linked list.
The head of a linked list is the item that comes first in the list's traversal. A linked list differs greatly from other data structures in several important ways. These pertain to linked list operations, memory allocation, and the data structure's inner structure.
Locating a specific item in a linked list takes more time than it does in an array, where indexing speeds up the search process. In contrast, a linked list requires the operation to begin from the root and proceed all the way to the element being sought. When compared to this, adding or removing components from linked lists from the outset is a breeze.
Stack
As with other data structures that employ LIFO (last-in, first-out) or FILO (first-in, last-out) ordering, a stack stores its elements in a sequential fashion (First In Last Out). A stack is related to two distinct kinds of operations: pushing and popping.
When a new item needs to be added to a collection, the pop method is used, while push is used to remove the last item from the collection. Only the most recently introduced ingredient is accessible for extraction.
To eliminate recursion, the stack might be used. Stacks are employed in situations requiring the inversion of a single letter, or in editors where the last character entered is erased before any other characters are undone.
Queue
When elements are being stored, a queue is used to ensure that FIFO (First In, First Out) is strictly adhered to (FIFO). To get the job done, the necessary operations are carried out on the elements in the specified order. As opposed to a stack, in which the most recently added item is removed first, a queue removes elements from the beginning of the queue. In a queue, on the other hand, the items are eliminated in the order in which they were introduced.
When adding or removing information from a data structure, both operations occur at its tail. Enqueue and dequeue are the two primary operations that determine the queue's architecture. The terms enqueue and dequeue relate, respectively, to the operations whereby new data can be added to and removed from a queue, and to the operation whereby the first item in the queue can be removed.
Queue structure illustration: The data structure is organized in the same way as physical queues, such as those formed when waiting for a bus or other service. Someone who arrived at the bus stop first would naturally take the first available spot in line. This person will leave the line of waiting passengers first and board a bus. Whenever several users are vying for a limited set of resources and must be served in the order in which they were added to the queue, queues are implemented.
