Cartesian Product Inset theory a Cartesian product is a mathematical operation that returns a set (or product set or simply product) from multiple sets.That is, for sets A and B, the Cartesian product A × B is the set of all ordered pairs (a, b) where a ∈ A and b ∈ B.We are required to write a JavaScript function that takes in two arrays let us call them arr1 and arr2, they both represent two distinct sets.The function should construct a 2-D array that contains the cartesian product of those two sets and finally return that array.ExampleFollowing is the code ...

We are required to write a JavaScript function that takes in multiple arrays of numbers. The function should return an array of the cartesian product of the elements from all the arrays.For example −If the input arrays are −[1, 2], [10, 20], [100, 200, 300]Then the output should be −const output = [ [ 1, 10, 100 ], [ 1, 10, 200 ], [ 1, 10, 300 ], [ 1, 20, 100 ], [ 1, 20, 200 ], [ 1, 20, 300 ], [ 2, 10, 100 ], [ 2, 10, 200 ], [ 2, 10, 300 ], [ 2, 20, 100 ], [ 2, 20, 200 ], [ 2, 20, 300 ] ];Exampleconst arr1 = [1, 2]; const arr2 = [10, 20]; const arr3 = [100, 200, 300]; const cartesianProduct = (...arr) => { return arr.reduce((acc,val) => { return acc.map(el => { return val.map(element => { return el.concat([element]); }); }).reduce((acc,val) => acc.concat(val) ,[]); }, [[]]); }; console.log(cartesianProduct(arr1, arr2, arr3));OutputThis will produce the following output −[ [ 1, 10, 100 ], [ 1, 10, 200 ], [ 1, 10, 300 ], [ 1, 20, 100 ], [ 1, 20, 200 ], [ 1, 20, 300 ], [ 2, 10, 100 ], [ 2, 10, 200 ], [ 2, 10, 300 ], [ 2, 20, 100 ], [ 2, 20, 200 ], [ 2, 20, 300 ] ]
Currently there are lots of professional cartoonizer applications available in the market but most of the them are not freeware. In order to get the basic cartoon effect, we just need the bilateral filter and some edge dectection mechanism. The bilateral filter will reduce the color palette, which is essential for the cartoon look and edge detection is to produce bold silhouettes.We are going to use openCV python library to convert an RGB color image to a cartoon image.AlgorithmFirstly apply the bilateral filter to reduce the color palette of the image.Then conver the actual image to grayscale.Now apply the median ...

In simple terms, website architecture is the visual and technical structure of the website. Web designers generally use the term while planning, designing, and developing a website. Technically, a website architecture is a logical website layout created per the user and business requirements. It is a collection of components that comprise a website and its services to the user. You can classify the components of website architecture into four parts Visual − It includes the user interface, buttons, colors, and other visual elements. Functional − It includes the type of services the website will provide. Technical − It ... Read More
Introduction Protein synthesis, the process of creating proteins from amino acids, is a fundamental process in all living organisms. This process requires the cooperation of many different molecules, including ribosomes, transfer RNAs (tRNAs), and aminoacyl tRNA synthetases (aaRSs). In this article, we will focus on aaRSs, the enzymes that attach amino acids to tRNAs, which are essential for the correct reading of the genetic code and the accurate synthesis of proteins. What is Aminoacyl tRNA synthetase? Aminoacyl tRNA synthetases (aaRSs) are enzymes that catalyze the attachment of specific amino acids to their corresponding tRNAs, a process called aminoacylation ... Read More
If you've been using command line interface on your computer, then you must be familiar with Bash, a popular shell that is used to run commands and scripts. Bash is a powerful tool that can help you automate various tasks and make your life easier. One of most important constructs in Bash is if-elif-else statement, which allows you to make decisions based on conditions. In this comprehensive tutorial, we will explore Bash if-elif-else statement and show you how to use it effectively. What is Bash if-elif-else Statement? The Bash if-elif-else statement is a construct that allows you to execute a ... Read More
If you're a Linux or Unix user, you're probably familiar with Bash, command-line shell that's commonly used on these systems. Bash has a lot of powerful features that can make working on command line much more efficient, and one of those features is called a "HereDoc." In this tutorial, we'll explain what a HereDoc is, how it works, and give you some examples of how you can use it in your Bash scripts. What is a HereDoc? A HereDoc, short for "Here Document, " is a way to include a block of text within a Bash script. This block of ... Read More
Bash is one of most commonly used shells in Unix-based operating systems. It is a command-line interface that allows users to interact with system and execute various commands. Bash is an essential tool for system administrators, developers, and programmers. One of features of Bash is ability to export variables. In this article, we will discuss basics of exporting variables in Bash, how it works, and examples of how to use it. What is a Bash Export Variable? A Bash export variable is a variable that is made available to all child processes of current shell. When a variable is exported, ... Read More
Introduction This article will teach you how to create a C# program that uses LINQ to generate odd numbers in parallel. Let's take a quick look at the language. The creation of desktop, online, and mobile apps generally uses the C# programming language. One of the strengths of C# is Linguistic Integrated Query, or LINQ. Data from many sources, including arrays, collections, and databases, can be rapidly accessed by developers. It provides a common syntax for data queries, regardless of the data source. As the syntax of LINQ and SQL is similar, developers can quickly understand and use them. ... Read More
Introduction The process of developing organs from three germ layers is called organogenesis. Cell-cell communication, cell fate determination, cell survival and proliferation, cell and tissue size and shape, and the organization of cells into tissues and ultimately functioning organs are all covered. The process through which cells in an embryo's initial germ layers specialize and take on the properties of the tissues that they eventually give rise to is called histogenesis. Research in regenerative biology is based on the study of organogenesis since the production of cells and tissues in vivo and in vitro frequently uses regulatory processes that ... Read More
