It is a complex type of a linked list in which a node has two links, one that connects to the next node in the sequence and another that connects to the previous node. This allows traversal across the data elements in both directions.

Examples include:

  • A music playlist with next and previous navigation buttons
  • The browser cache with BACK-FORWARD visited pages
  • The undo and redo functionality on a browser, where you can reverse the node to get to the previous page

What Are Data Structures And Algorithms

Data structures and algorithms are everywhere, and there is a good reason for that. Data structures help us hold data and provide affordances for efficiently manipulating it, while algorithms represent tried-and-tested computational recipes to accomplish particular goals. Let me explain how it all works.

Human thinking may seem flexible and seemingly unconstrained, but in truth, we have a flurry of biological limitations. For instance, we typically can only hold in our short-term memory about 7 items the famous magical number 7.

Well, computers have similar limitations. They have limited resources that constrain what can be accomplished with software in a number of ways: computers can only store so much data in memory, and computers can only perform so many operations per second most notably, CPUs.

That said, there are many ways of taking advantage of computer resources, some more efficient than others. Data structures in particular, as their name suggests, allow to organize information in such a way that it can efficiently be leveraged in certain contexts. There are many data structures, each with their strengths and weaknesses. A good developer should know the fundamental data structures and when to use each. Theyre essential components of many applications, and theyre ubiquitous in high-performance computing.

Can You Explain The Difference Between File Structure And Storage Structure

Pin on Fundamentals Of Data Structures
  • File Structure: Representation of data into secondary or auxiliary memory say any device such as a hard disk or pen drives that stores data which remains intact until manually deleted is known as a file structure representation.
  • Storage Structure: In this type, data is stored in the main memory i.e RAM, and is deleted once the function that uses this data gets completely executed.

The difference is that the storage structure has data stored in the memory of the computer system, whereas the file structure has the data stored in the auxiliary memory.

Why Do We Need To Do An Algorithm Analysis

A problem can be solved in more than one way using several solution algorithms. Algorithm analysis provides an estimation of the required resources of an algorithm to solve a specific computational problem. The amount of time and space resources required to execute is also determined.

The time complexity of an algorithm quantifies the amount of time taken for an algorithm to run as a function of the length of the input. The space complexity quantifies the amount of space or memory taken by an algorithm, to run as a function of the length of the input.

    What Are Some Examples Of Divide And Conquer Algorithms

    Data Structures And Algorithms Course

    Quicksort is the name of a sorting algorithm. The method selects a pivot element and rearranges the array elements so that all items less than the pivot chosen element go to the left side of the pivot and all elements more significant than the pivot element move to the right side.

    Merge Sort is a sorting algorithm as well. The algorithm divides the array into two halves, sorts them recursively, and then combines the two sorted halves. The goal of points that are closest together is to identify the nearest pair of points in an x-y plane collection of points. The issue may be solved in O time by computing the distances between each pair of locations and comparing them to determine the shortest distance.
