How Many Functions Are There in Data Structure?


Larry Thompson

In the field of data structures, functions play a vital role in manipulating and accessing data efficiently. A function is a block of code that performs a specific task and can be reused multiple times throughout a program. In this article, we will explore the various functions commonly used in data structures.

1. Insertion Functions

Insertion functions are used to add new elements into a data structure. These functions are crucial for maintaining the integrity of the structure and ensuring that the added elements are properly placed.

1.1 Insert at Beginning

To insert an element at the beginning of a data structure, we use the insertAtBeginning() function. This function shifts all existing elements to the right and places the new element at the beginning.2 Insert at End

The insertAtEnd() function is used to add an element at the end of a data structure. It ensures that all existing elements remain intact while appending the new element.

2. Deletion Functions

In contrast to insertion functions, deletion functions remove elements from a data structure.

2.1 Delete from Beginning

The deleteFromBeginning() function removes an element from the beginning of a data structure. It shifts all remaining elements to fill in the vacant space created by deletion.2 Delete from End

To remove an element from the end of a data structure, we use the deleteFromEnd() function. This function ensures that all remaining elements stay intact while removing the last one.

3. Search Functions

Data structures often require searching for a specific element.

3.1 Linear Search

The linearSearch() function is used to search for an element in a linear data structure such as an array or a linked list. It checks each element one by one until a match is found.2 Binary Search

In case of sorted data structures like binary trees or sorted arrays, the binarySearch() function is used. This function repeatedly divides the search space in half until the desired element is found.

4. Access Functions

Data structures provide various functions to access and retrieve elements efficiently.

4.1 Access by Index

The accessByIndex() function allows accessing an element at a specific index in a data structure such as an array or a list. It returns the value stored at the given index position.2 Access by Key

In key-based data structures like maps or dictionaries, we use the accessByKey() function to retrieve values associated with a particular key.

5. Sorting Functions

Data structures often require sorting elements in ascending or descending order.

5.1 Bubble Sort

The bubbleSort() function compares adjacent elements and swaps them if they are in the wrong order, gradually moving larger elements towards the end of the list.2 Quick Sort

The quickSort() function uses divide-and-conquer strategy to partition and sort elements efficiently by selecting a pivot and rearranging elements around it recursively.

  • Conclusion: Functions in data structures are essential for performing various operations efficiently. From insertion and deletion to searching, accessing, and sorting, these functions enable us to manipulate and manage data effectively.

By understanding the different functions available in data structures, developers can choose the most suitable approach for their specific requirements.
