Basic data structures and algorithms









The entry point in a linked list is called the head. Each node has two items: a data field and a reference to the next node.

Each element is a separate object, called a node. The elements are linked using pointers to form a chain. It’s a linear Data Structure or a sequence of data objects where elements are not stored in adjacent memory locations. Try to explain as much as possible rather than finishing your answer in a sentence! This is one of the most frequently asked data structure interview questions where the interviewer expects you to give a thorough answer. The first column of the array is entirely saved in memory, followed by the second row of the array, and so on until the last column of the array is wholly recorded in memory. Column-Major Order: In column-major ordering, all of the columns of a 2D array are stored in memory in the same order.Row-Major Order: -In row-major ordering, all of the rows of a 2D array are stored in memory in a contiguous manner.įirst, the first row of the array is entirely stored in memory, followed by the second row of the array, and so on until the final row.How are the elements of a 2D array stored in the memory? We need to notify C that we have two dimensions for a two-dimensional array. Declaring a multidimensional array is the same as saying a one-dimensional array. A 2D array is also referred to as a matrix or a table with rows and columns. As you'll see in the code, it's technically an array of arrays. The 2D array, or two-dimensional array, is the most basic multidimensional array. It is an array of arrays or an array with numerous layers. What is a multidimensional array?Ī multidimensional array is a multidimensional array with more than one dimension. Storage structure refers to the data structure in the memory of the computer system, whereas file structure represents the storage structure in the auxiliary memory. The difference lies in the memory area accessed.

What is the difference between file structure and storage structure? Numerical analysis, operating system, AI, compiler design, database management, graphics, statistical analysis, and simulation. What are some applications of Data Structures? The elements are stored in a non-hierarchical way so that each item has successors and predecessors except the first and last element in the list.Įxamples of linear data structures are Arrays, Stack, Strings, Queue, and Linked List. What is a Linear Data Structure? Name a few examples.Ī data structure is linear if all its elements or data items are arranged in a sequence or a linear order. These are comparable to records in that the outcome or alteration of data is mirrored across the whole table.ģ.

  • Tables: The data is saved in the form of rows and columns.
  • This form of data structure follows the ordered order of data item insertion, deletion, and modification.
  • Trees: A data structure that organizes data in a hierarchical framework.

    Records: A collection of fields, each of which contains data from a single data type.Arrays: A collection of values that are all the same.Lists: A collection of related things linked to the previous or/and following data items.The following are the types of data structures: It also defines the way different sets of data relate to one another, establishing relationships and forming algorithms. The Data Structure is the way data is organized (stored) and manipulated for retrieval and access.
