Computer Graphics It is an art of drawing pictures, lines, charts, etc, on the computer screen by using a programming language. For the creation and manipulation of pictures on display devices as well as storing, modifying, representing images computers will be used often. In computer graphics objects are introduced as a group of discrete image …
THEORY OF COMPUTATION (TOC) Previous Next Introduction of Theory of Computation (TOC) Automata theory (also identified as Theory Of Computation) is a theoretical department of Computer Science and Mathematics, which mostly concerned with the good judgment of computation with respect to straight forward machines, generally known as automata. The key motivation in the back of constructing the …
Previous Next Tree Tree can be defined as a collection of entities (nodes) linked together to simulate a hierarchy. Some Terminology That Is Used In Tree NODE Each data item in a tree. degree of node The total numvber of childeren associated with a nodes. degree of a tree Highest child of a node in …
Time Complexity and Space Complexity Previous Next How do you do “measure” your code? Would you clock “how long” it takes to run? What if you are running the same program on a mobile device or a quantum computer? The same code will give you different results. To answer these questions, we need to nail …
QUEUES Previous Next Types Of Queue In Data Structure (Queue Variations) The standard queue data structures have the following variations: Simple Queue (Queue) Double-ended Queue (deque) Circular Queue Priority Queue What Is The Queue And How It Differs From The Stack We can also say that a queue is a sequentially ordered list where insertions …
Expression Parsing (Infix, Prefix and Postfix) Previous Next Any arithmetic expression can be written in three different but equal notations, i.e. without modifying an expression’s meaning or output. Those notations are − Infix Notation Prefix (Polish) Notation Postfix (Reverse-Polish) Notation Expression Parsing There are 3 types of notation we read in the first paragraph. We will read …
Stack Previous Next Before going to the stack, we will read the enclosure of Abstract Data Types (ADT) extensively. What is ADT, what methods come in it and which stack is used? At the same time, we will also read and understand the functionality of each method of Abstract Data Types. What is an Abstract …
Array Previous Next . What is an Array? An array is a collection of similar data types that store items in contiguous memory locations. It is also known as the Subscripted variable. Arrays are very powerful data structures that store lists of elements Arrays are classified as Homogeneous Data Structures because they store elements of …
