Array is a data structure in which elements are stored in continuous memory location (memory representation ), continues allocation of elements takes place in arrays, Linked list consist of Data and Reference. Array has random access permissions and Link list has sequential access permissions. Both Array & Linked List organizes data differently.
Insertion and deletion process completion time is higher in array then in linked list. Array has static memory allocation that means that the memory for array will be allocated for an array during compile time.
Array will have sequential data representation.
Array types : 1 dimensional / 2 d dimensional / 3 dimensional / multi-dimensional array,
Array is linear in nature and hence is a linear data structure.
Linked List
Element are stored in random discreet memory location. (Discreet memory representation ) (allotment based), linked list ensures non continuous allocation of data elements.
Linked list has sequential data access and the data flow is based on linked list types, there are three types of linked lists:
SLL -> SINGLE LINKED LIST
DLL -> DOUBLE LINKED LIST
CLL -> CIRCULAR LINKED LIST
- Linked list have dynamic memory allocation (it is flexible in nature, changes are accepted during runtime). Memory will be allocated for linked list during runtime.
- Linked list have linked representation of data (Link data representation)
- Linked list is linear data structure like array.
USE CASES: The properties, types and schema of both the array and linked list is different hence both of them are leveraged based on the specific use cases, some operations can be faster and efficient with arrays and some processes and operations can be faster with linked lists.
The Data structure usage and implementation is based on the use case and hence both the array and linked list will be processed via DSAs to carry out computational tasks.
Be it linked list or be it array both of them will be processed via dsa. Both the input and the output will be in the same DS format, if the input is in LINKED LIST output will be in LINKED LIST, if the input is in array then the output will be Array, the conversion of the linked list to array and vice versa can be carried out based on the computational and presentation needs.
