What is Shell Sort in Data Structure? Shell sort is one of the oldest sorting(ascending order) algorithms named after its inventor Donald L. Shell (1959). Shell Sort is a sorting algorithm that is an improved version of Insertion Sort. It works by comparing and exchanging elements that are far apart, progressively reducing the gap between … Read more
What is an Array Introduction An array is a data structure that stores multiple items of the same data type. Unlike Python’s built-in lists, which can store different data types, arrays are designed for homogenous data storage (e.g., only integers or floats). This feature makes arrays more efficient in memory and computation, especially for numerical data. … Read more
Introduction to Recursion in C Data Structures Recursion in data structure is a process where a function calls itself to solve smaller instances of the same problem until it reaches a base case, which stops the recursion. It is a fundamental concept used in programming and data structures to solve complex problems in a simpler, … Read more
Queue Operations are…… 1· Enqueue—Add an item(new item in the backside) to the end of the queue. 2· Dequeue—Remove an item from the front. 3· Queue Front—Who is first? 4· Queueu End—Who is last? What is the Queue algorithm in the C data structure? 1)Storage for a queue….. Struct intqueue { int *queueAry; int maxSize; int countt; int … Read more
The structure of a C program is typically organized into several parts. Here’s an outline of the key components of a basic C program: 1.Preprocessor Directives These are instructions to the C preprocessor. They usually include library imports or macro definitions and start with #. Common examples: #include <stdio.h> // For input/output functions #include <stdlib.h> … Read more
Algorithm for creation in a Linked List CREATE—In this algorithm, a Linked List of nodes is created. The list is pointed by pointer first, the last node of the list points to NULL., indicating the end of the list. Each node has two parts DATA and NEXT. Let us assume that a linked list of … Read more
The array is also called a constant pointer. This pointer points to the first element of the array. Whenever you create an array, this pointer is automatically created. So, if you assign an array name to a pointer variable, then there is no need to use an address of the (&) operator before the name … Read more
This Java program source code converts temperature from Fahrenheit to Celsius scale. import java.util.*; class FahrenheitCelsius { public static void main(String[] args) { float temp; Scanner inn = new Scanner(System.in); System.out.print(“Enter temperature in Fahrenheit=”); temp= inn.nextInt(); temp = ((temp – 32)*5)/9; System.out.println(“Temperature in Celsius = ” + temp); } } In the above program, you … Read more
Write a program in Java to Swap two digits using a third variable. import java.util.Scanner; class Swapping { public static void main(String args[]) { int first_no, sec_no, third_no; System.out.println(“Enter first_no and sec_no”); Scanner in = new Scanner(System.in); first_no = in.nextInt(); sec_no = in.nextInt(); System.out.println(“Before Swapping\nfirst_no = “+first_no+”\nsec_no = “+sec_no); third_no = first_no; first_no = sec_no; … Read more
In this tutorial, I am going to show you how to take input from users in Java using two different ways. You can follow any method(Scanner, Buffered) according to your convenience. To understand how we get input from users in Java we first must know the following two things : System.out – Java uses System.out to … Read more
