It also comes in varieties like a singly linked list, which allows you to traverse in one direction (forward or reverse) a doubly-linked list, which allows you to traverse in both directions (forward and backward) and finally, the circular linked list, which forms a circle. This article provides more information on the difference between an array and linked list data structures. However, unlike the array, it doesn’t store them in contiguous locations instead, they are scattered everywhere in memory, which is connected to each other using nodes.Ī linked list is nothing but a list of nodes where each node contains the value stored and the address of the next node.īecause of this structure, it’s easy to add and remove elements in a linked list, as you just need to change the link instead of creating the array, but the search is difficult and often requires O(n) time to find an element in the singly linked list. Similar to the array, it is also a linear data structure and stores elements in a linear fashion. What is a linked list data structure?Ī linked list is another common data structure that complements the array data structure. It will also make you a better programmer because you develop logic and coding sense while solving these problems which goes a long way in your programming career.
In the past, I have shared some data structure questions, string algorithms problems, and some useful online courses to prepare for Programming Job Interview and today I am going to share a list of frequently asked linked list problems from coding interviews.ĭata Structures are one of the most important parts of any programming Job interview and often the reason to select or reject a candidate, that’s why practicing these data structure based problems will give you an edge over your competitor.
Hello all, I have been sharing a lot of coding interview questions for Programmers who are actively looking for Job, particularly for beginners and computer engineers who have just graduated and has no real job experience.
