Write a C program to reverse a linked list. Given a singly linked list, we have to write a code to reverse a linked list. In this tutorial, we are going to use iterative approach to solve this problem.
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.
Through recursion, you can reduce complex problem into smaller version.
Write a java program to find duplicate elements in an array. There are multiple ways through which we can find duplicate elements in an array. In this tutorial, I’ll discuss three ways to find duplicate elements in an array.
This question is also very important in terms of technical interviews.
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.
Programming questions on linked list
Swap two numbers using Bitwise XOR Operator
Write a C program to print hello world without using semicolon. It’s an interesting problem, As in C code every line is terminated with a semicolon. So, how do we write a c program to print hello world without using semicolon. This problem is also important in terms of interview.
