Write a stack program in C using an array. Implement a stack data structure using an Array. In this tutorial, We’ll learn about stack data structure and it’s implementation using an array.
What is a Stack in Data Structure?
A Stack is a Data Structure, in which insertion and deletion operations are allowed only at one end. It worked on LIFO (Last In First Out) Principle. In LIFO, an element which inserted last must be the first element to be removed.
Write a C program to reverse a singly linked list. Given a linked list, write a method to reverse a singly linked list. In this tutorial, we are going to write a code to reverse a linked list using an iterative approach.
Write a C program to insert a node at the beginning of linked list. In this tutorial, we create a linked list and insert a new node at the beginning/head of linked list.
A Linked list is a linear data structure which consists a group of nodes and each node points to next node by means of a pointer. In Linked list, a node consists of two parts, a data and a pointer to next node.
What is recursion and how to use recursion in programming. If you are new to programming, then recursion concept is tough to understand. In this post, i’ll explain the concept of recursion with example.
What is Recursion ?
In Recursion, function call itself repeatedly, until the base condition is reached. It’s a much preferred way to write cleaner and shorter code for many complex problems.
Write a selection sort program in C. How selection sort algorithm works and what’s their time complexity.
What is Selection Sort
Selection sort is an in-place comparison sort. Like bubble sort time complexity of Selection sort is also O(n^2). It is not suitable for large elements.
Bubble Sort program, Algorithm & their time complexity.In this tutorial, We are going to learn about bubble sort algorithm and their implementation in various programming languages.
In this tutorial, we are going to cover following things
- What is Bubble Sort?
- Bubble sort algorithm & it’s time complexity
- Bubble sort program in C & C++
- Java program to implement Bubble sort
- Bubble sort implementation in PHP
What is Bubble Sort?
Bubble sort is a sorting algorithm, It works by comparing each pair of adjacent elements and switching their positions if necessary. It repeats this process until all the elements are sorted.
Write a c program to swap two numbers without using third variable. Given two input numbers, We have to write a code to swap two numbers without using third variable. In my previous post, I have explained a c program to swap two numbers using third variable. This question is generally asked in an interview.
Write a c program to swap two numbers using third variable. Given two input integers, We have to write a code to swap two numbers using a third or temporary variable.
