No, two IP addresses cannot be the same in a single network as each IP address serves as a unique identifier for a device connected to a network. In IPv4, an IP address is a 32-bit binary number, typically represented in dotted-decimal notation, that uniquely identifies a device on a TCP/IP network. In IPv6, an IP address is a 128-bit binary number, represented in hexadecimal notation, that also uniquely identifies a device on a TCP/IP network. IP Address Structure An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol ... Read More
Using JavaScript or jQuery, we can check whether a file exists and retrieve metadata about the file, such as its size, content type, last modified date, etc., without retrieving the actual file. The HTTP HEAD request is used in this case. An HTTP HEAD request is a type of HTTP request that asks the server to return the HTTP headers for a specified resource without the actual resource itself. Several methods can be used to send an HTTP HEAD request, but the most popular way is to use the $.ajax() method and XMLHttpRequest object. Users can define the request ... Read More
JavaScript is a loosely typed programming language, meaning there is no such rule to declare the variable type. A variable can store multiple data types in a program, so it is essential to understand the variable type before using it. In JavaScript, we can use the typeof operator to check the type of a variable or object. The typeof operator takes a variable and returns its type in a string format. In addition, to the typeof operator, JavaScript also provides the instanceof operator to check the type of a variable or object. The instanceof operator accepts two arguments: the ... Read More
The Caesar Cipher is a simple substitution cipher named after Julius Caesar, who reportedly used it to communicate with his officials. The technique involves shifting each letter in a message by a fixed number of positions in the alphabet. For example, with a shift of 3, A would be replaced by D, B would become E, and so on. The Caesar Cipher is relatively easy to break and is considered to be a very weak form of encryption, but it served its purpose for Julius Caesar. It's still used for educational and recreational purposes. Algorithm for Caesar Cipher Here is ... Read More
We mainly use JavaScript to create dynamic web applications. This kind of scripting language makes a web page look interactive. JavaScript significantly adds some logic to our website. As we mentioned, the user can check whether the background image is loaded. Web developers can understand that the page is loaded correctly and that the background image is displayed properly. To check whether the background image is loaded as directed by the web developers on the web page user can use the image object. We can access this object's properties and methods related to an image, and we can apply ... Read More
Keywords are reserved words used to perform some internal process or represent predefined actions. It is not allowed to use these keywords as a variable name, constant name, or identifier. Swift support approx 101 keywords. For example, ‘var’ is a keyword but ‘hey’ is not a keyword. Here, we will learn how to write a swift program to check whether a given string is a keyword. Algorithm Step 1 − Create an array of string types to store all the keywords supported by Swift. Step 2 − Create a function to check if the given string is a ... Read More
A palindrome array is an array that remains the same when its elements are reversed we can also say that the elements of a palindrome array remain the same even if we read it from backward or forward. For example, [1, 9, 10, 9, 1] is a palindrome array whereas [3, 5, 7, 8, 3, 2, 1] is not a palindrome array. In this article, we are going to learn different methods of finding whether the given array is a palindrome or not suing Swift programming language. Algorithm Step 1 − Create a function. Step 2 − Reverse the ... Read More
An array is used to store elements of the same data type in an order whereas a set is used to store distinct elements of the same data type without any definite order. To convert Array into set we use Set() initialiser. The resultant set contains the same elements as the original array but with no order and no duplicate elements. In this article, we will learn how to convert Array to Set using Swift programming language. Algorithm Step 1 − Create an array of integer type. Step 2 − Print the array. Step 3 − Convert array into ... Read More
1’s complement of a binary number is the invert of the given number. For example, we have a number = 10101011, so the one’s complement is 01010100. Here we using the following two methods to find one’s complement − Replacing 1s with 0s and 0s with 1s Using XOR In this article, we will learn how to write a swift program to find the 1’s complement of the given number. Method 1: Replacing 1s with 0s and 0s with 1s It is the smallest method to find ons complement of the given number. Here we simply convert the given number ... Read More
A strong number is a special number in which the sum of the factorial of its digit is equal to the number itself. For example − Number = 345 345! = 3! + 4! + 5! = 6 + 24 + 120 = 150 Here 345 is not a strong number because the sum of the factorial of its digit is not equal to the number itself. Number = 145 145! = 1! + 4! + 5! = 1 + 24 + 120 = 145 Here 145 is a strong number because the sum of the factorial of its ... Read More
