Inside a computer, there is an Arithmetic Logic Unit (ALU), which is capable of performing logical operations (e.g. AND, OR, Ex-OR, Invert etc.) in addition to the arithmetic operations (e.g. Addition, Subtraction etc.). The control unit supplies the data required by the ALU from memory, or from input devices, and directs the ALU to perform a specific operation based on the instruction fetched from the memory. ALU is the “calculator” portion of the computer.An arithmetic logic unit(ALU) is a major component of the central processing unit of the a computer system. It does all processes related to arithmetic and logic ... Read More
In MATLAB, there are three logical operators namely, logical AND (&&), logical OR (||), and logical NOT (~). The "if" is a conditional statement used to develop control expressions in MATLAB programming. In this tutorial, I will explain the use of logical operators within if statements in MATLAB. What is Logical AND Operator in MATLAB? In MATLAB, the logical AND operator is a binary operator that takes two operands to execute. It is denoted by "&&". The result of the logical AND (&&) operator is considered true (1) only if both of its operands or conditions are true (1). If ... Read More
A matrix is a structure which is used to store and work with numeric data. Each value stored in a matrix is referred to as an element. Sometimes, we need to swap or change the position of these elements within the matrix. We can use MATLAB to perform this task i.e., swapping the elements of the matrix. In this tutorial, I will explain how we can use MATLAB to swap the elements in a matrix. Swap Elements in a Matrix MATLAB is a powerful tool that can be used to manipulate matrices. It provides various methods to swap the elements ... Read More
In MATLAB, we can perform various operations on matrices. One such operation is selecting random rows from a matrix. MATLAB provides several different methods of selecting random rows from a matrix. In this tutorial, I will explain different methods of selecting rows from a matrix randomly using MATLAB. Select Random Rows from a Matrix in MATALB In MATLAB, we have various built-in functions that can be used to randomly select rows from a matrix. The following are some commonly used functions to randomly select rows from a matrix − randperm() Function randsample() Function randi() Function datasample() Function Let ... Read More
Circuit SwitchingCircuit Switching is a connection-oriented service. It provides a dedicated path from the sender to the receiver. In-circuit switching, a connection setup is required to send and receive data. It has very little chance of data loss and error due to the dedicated circuit, but a lot of bandwidth is wasted because the same path cannot be used by other senders during a congestion. Circuit switching is completely transparent; the sender and receiver can use any bit rate format or framing method.Advantages of Circuit SwitchingIt uses a fixed bandwidth.A dedicated communication channel increases the quality of communication.Data is transmitted ...

An event is defined as a change in an object's state. There are a number of events in HTML that show when a user or browser performs a certain action. JavaScript responds to these events when JavaScript code is embedded in HTML and allows execution. The process of responding to events is known as event handling. As a result, JavaScript uses event handlers to handle HTML events. In this article, we are going to discuss how to remove event handlers in JavaScript. Here, we use the removeEventListener() method to remove an event handler from an element in JavaScript. Using the ... Read More
Rounding toward negative infinity is a method of rounding a number "N" down to the nearest integer less than or equal to the number "N". This method is also called "flooring". In simple words, rounding a number toward negative infinity is a method of finding the largest integer number which is less than or equal to the given number. For example, consider a number 4.8, when this number is round to negative infinity. Then, it will become 4. This is because, 4 is the largest integer number less than or equal to 4.8. Similarly, if we have a negative ... Read More
Sometimes you might have noticed that the default search engine of your Chrome browser is automatically changed to Bing. If this is happening without any user intervention, it might be because of malware known as Browser Hijacker. Browser Hijacker takes control of your browser and modifies its settings for conducting malicious activities, including changing the default search engine, homepage, and others. In this post, we would discuss how Bing become your Chrome browser's default search engine and how to remove it from Chrome. What is Bing? Bing is one of the most popular search engines on the internet world. In ... Read More
Problems involving grids and matrices are mostly solved using either BFS or DFS traversal algorithms. Taking a look into the first one, Breadth First Traversal − BFS or Breadth First Traversal is an algorithm for searching a tree or a graph data structure. It starts at the root node and explores all the nodes at the present level before moving on to the next level. Algorithm procedure BFS(G, root) is let Q be a queue label root as explored Q.enqueue(root) while Q is not empty do ... Read More
Reducing an array to a single element by repeatedly removing element is done by the following criteria − Select indices i and j such that i < j and arr[i] < arr[j] and convert one of the two elements to 0. Problem Statement Given an array arr[] containing positive integers. Find if the array can be reduced to a single element by repeatedly removing an element from any increasing pair. If possible return true along with the indices chosen and the index of the element that is removed. Sample Example 1 Input arr[] = {5, 7, 10, 2, 4, ... Read More
