Additionally, we have authored public notes about VisuAlgo in various languages, including Indonesian, Korean, Vietnamese, and Thai: id, VisuAlgo has been translated into three primary languages: English, Chinese, and Indonesian. Each VisuAlgo visualization module now includes its own online quiz component. By assigning a small (but non-zero) weight to passing the online quiz, CS instructors can significantly enhance their students' mastery of these basic concepts, as they have access to an almost unlimited number of practice questions that can be instantly verified before taking the online quiz. As more CS instructors adopt this online quiz system worldwide, it could effectively eliminate manual basic data structure and algorithm questions from standard Computer Science exams in many universities. Questions are randomly generated based on specific rules, and students' answers are automatically graded upon submission to our grading server. At present, the platform features 24 visualization modules.Įquipped with a built-in question generator and answer verifier, VisuAlgo's "online quiz system" enables students to test their knowledge of basic data structures and algorithms. VisuAlgo remains a work in progress, with the ongoing development of more complex visualizations. However, since April 2022, a mobile (lite) version of VisuAlgo has been made available, making it possible to use a subset of VisuAlgo features on smartphone screens. For an optimal user experience, a minimum screen resolution of 1366x768 is recommended. Initially, VisuAlgo was not designed for small touch screens like smartphones, as intricate algorithm visualizations required substantial pixel space and click-and-drag interactions. While primarily designed for National University of Singapore (NUS) students enrolled in various data structure and algorithm courses (e.g., CS1010/equivalent, CS2040/equivalent (including IT5003), CS3230, CS3233, and CS4234), VisuAlgo also serves as a valuable resource for inquisitive minds worldwide, promoting online learning. Suhendry Effendy - VisuAlgo remains the exclusive platform for visualizing and animating several of these complex algorithms even after a decade. Steven Halim's book, 'Competitive Programming' - co-authored with Dr. Steven Halim, VisuAlgo aimed to facilitate a deeper understanding of data structures and algorithms for his students by providing a self-paced, interactive learning platform.įeaturing numerous advanced algorithms discussed in Dr. Therefore, their implementations are also quite similar.Initially conceived in 2011 by Dr. The stack ADT is very similar to the list ADT Object dequeue() remove and return the item from the front of the queue Void enqueue(Object ob) add ob to the rear of the queue Int size() return the number of items in the queue Queue() (constructor) create an empty queueīoolean empty() return true iff the queue is empty The only item that can be removed is the one at the front of Items can only be added at the rear of the queue, and Values in -> items in the queue -> values outĪ queue is a First-In-First-Out (FIFO) data structure. The conceptual picture of a queue is something like this: Not remove it (error if the stack is empty) Object peek() return the item that is on the top of the stack, but do Object pop() remove and return the item from the top of the stack Void push(Object ob) add ob to the top of the stack Int size() return the number of items in the stack Stack() (constructor) create an empty stackīoolean empty() return true iff the stack is empty The only item that can be taken out (or even seen) is the most recentlyĪdded item a stack is a Last-In-First-Out (LIFO) data structure. Think of a stack of newspapers, or trays in a cafeteria. The conceptual picture of a stack is something like this: They can both be implemented either using an array or using a linked list Comparison of Array and Linked-List Implementationsīoth stacks and queues are like lists (ordered collections of items),.
