Golang program to create a module with constant
In the Go programming language, a module is a collection of packages and it helps to manage them and their dependencies. In this article, we will create a module with constant using two examples. In the first example, we will create a constant string that will be returned by the function and that function will be called from the main of another module. In the second example, a function will be created to return the string and print when called by the main of another module. Algorithm Import the required packages in the program Create a constant string in ...
Read MoreSwift Program to Check if a String is Numeric
To check if the given string is numeric or not we use Double() initializer in Swift Programming. A string is an ordered collection of characters for example “Sky”. A string can be numeric and non-numeric. A numeric string is a string which only contains numbers for example “12345”. So the valid numeric strings are: “3423”, “222333”, “34.342”, etc., whereas non-valid numeric strings are “23hfd23”, “423131sdd”, etc. So it converts the given string into double and return true if the given string is numeric otherwise return false. Algorithm Step 1 − Create a function Step 2 − Return ...
Read MoreSwift Program to get the flattened 1D array
Swift has various functions like flatmap(), compactmap(), reduce() to flatten an 1D array. An array is used to store elements of same data type in an order whereas a set is used to store distinct elements of same data type without any definite order. Method 1: Using flatmap() Function To flatten 2D array into 1D array we can use flatmap() function. The flatmap() function return an array by concatenating the sub arrays into a single array. Syntax func flatMap{_res} Here, res is a closure which accepts the element of the specified array as its argument and return a flattened ...
Read MoreSwift Program to get the subarray from an array using a specified range of indices
In swift, we have various methods like Array() initializer and for-in loop that can be used for getting the subarray from an array using a specified range of indices. An array stores elements of the same data type in an order. Let’s understand both the methods in detail in this article. Method 1: Using Array() initialiser To get the subarray from an array using a specified range of indices we uses Array() initialiser. Here we find the subarray using range operator and then convert the elements into the array using Array() initialiser. Algorithm Step 1 − Create an ...
Read MoreHow to Resize Matplotlib RadioButtons
Matplotlib is a popular data visualization library in Python that provides a wide range of tools for creating interactive plots and charts. One of the interactive components offered by Matplotlib is the RadioButtons widget, which allows users to select a single option from a group of mutually exclusive choices. While working with RadioButtons, you may encounter situations where you need to resize them to better fit your plot or application layout. In this article, we will explore different methods to resize Matplotlib RadioButtons. Syntax radio_buttons.ax.set_position([left, bottom, width, height]) Here, radio_buttons refers to the instance of the RadioButtons widget. ...
Read MoreDifference between CORBA and DCOM
The world of technology and programming has developed a variety of languages and frameworks, each with its functionality and purpose. This article examines the differences between these two great technologies. In this article, we will the concept of CORBA and DCOM and its difference. CORBA, which has a strong presence in the business field, and DCOM, Microsoft's technology, each have different characteristics. Understanding these differences is important for developers and businesses trying to make informed decisions about their tech stack. What is CORBA? CORBA (Common Object Request Broker Architecture) is a middleware innovation that empowers interoperability and communication between disseminated ...
Read MoreHow to delete an index from a JSON Object ?
While working with JSON objects, Sometimes we need to delete an index or key from the JSON object to remove unwanted data or modify the structure. We can delete the index from a JSON object using methods like the delete operator, filter method, and lodash library. In this article, we will explore these different methods to delete an index from a JSON object. Prerequisites To follow along with the examples provided in this article, you should have a basic understanding of JavaScript and JSON syntax. Additionally, you will need a text editor or an integrated development environment (IDE) to write ...
Read MoreHow to select ID that starts with certain character using jQuery ?
jQuery is a popular JavaScript library that simplifies the process of traversing and manipulating HTML documents. In web development, one common requirement is to select elements with specific attributes or properties. In this article, we will explore how to select HTML elements whose IDs start with a certain character using jQuery. Use of Selecting ID that starts with certain character Targeting Specific Groups of Elements: When working with a large number of elements, it may be necessary to group them based on a common identifier. By selecting IDs that start with a specific character, you can easily target and ...
Read MoreHow to concatenate two files into a new file using Python?
In Python, concatenation is a process that refers to combining two or more strings, lists, or such sequence-like objects into a single object. The concatenation operation when performed is denoted by using the "+" operator. Concatenating two files into a single file can be a useful process when you want to combine the contents of several files. If you want to merge data from different sources or simply create a consolidated file with aggregated data, Python provides a simple no-frills method to accomplish this task. In this article, we will explore different ways of concatenating two files into a ...
Read MoreHaskell Program to Check if a String is Numeric
In Haskell we can use read functions and Data.char library to find if a given string is numeric or not. The following example will give you a clear idea about the valid numeric values. For example, 121, 12321, and 1221 if entered as string are valid numeric values. Algorithm Step 1 − The isNumeric function using reads function is defined Step 2 − Program execution will be started from main function. The main() function has whole control of the program. It is written as main = do. In the main function, the string is passed to the isNumeric function. ...
