With everything going digital nowadays, the amount of data being generated has also gone up. • This has increased demand for data management jobs, which would require a data structures and algorithms training in Bangalore. • Data structures course online can be useful for app developers as well in many ways.
A data structure is a specific format for storing and organizing data. Generally, types of data structures include the file, the array, the record, the tree, the record, and many more. • A data structure is specifically designed to organize the data in order to suit some specific purpose so as to allow the user to access and manage the data in an appropriate manner.
Array • An array is a collection of elements in a precise order, and typically all are of same type. • The elements can be accessed with the use of an integer index in order to specify the element that is required (depending on language being used, each element individually may either be of any type, or may be forced to be of some particular type). • Typically, implementations are allocated for contiguous memory words for elements of the array, but this is not a necessity in all cases. Arrays could be resizable or of fixed-length.
Linked list • Linked list, or simply called list, is a collection of elements in a linear manner; the linear order of which is not provided by its physical location in the memory. • In linked list, each data element points to next element. It is a type of data structure, and consists of nodes that represent a sequence. • Each node in a linked list consists of data and a reference (or link) to next node that comes in the sequence. • This type of data structure allows an efficient removal and insertion of elements for various positions in the list sequence. • There are certain other operations, however, that are slower to execute using linked list such as accessing randomly a certain element.
Record • A record, also known as struct or structure, is an aggregate and basic data structure. It is a collection of various fields, of different types of data, generally in sequence and fixed number. • These fields that make up a record, can also be known as members, specifically in programming that is object-oriented. • Fields could also be known as elements; however, it may raise confusion with elements referring to collection. • The term record and tuple may or may not be used interchangeably, depending on the conventions, and the type of programming language being used.
Union • A union data type is a value which may take any of the several formats or representations within the same location in the memory; or a union is a data structure type that is composed of a variable that may contain such a value as a union data type. • Union types are special data types that that are supported by certain programming languages. • Join online data structures and algorithms course to get detailed knowledge about data management.
