Go language Program to calculate the sum of matrix elements
What is a Matrix? A matrix is a collection of numbers that are arranged in rows and columns, which is a two-dimensional array. Here we will use three examples to find the sum of elements and compare each element of the matrix for the same using the Golang program. Algorithm Step 1 − Import the fmt package. Step 2 − Now we need to start the main() function. Step 3 − Then we are creating a matrix naming matrixA. Step 4 − Print the matrix on the screen using fmt.Println() function. Step 5 − Initialize a new variable called ...
Read MoreHow to create Price Range Selector in ReactJS?
The price range selector allows us to select two values representing the range. Sometimes, we require to create a range slider to allow users to select a range. For example, we can allow users to select a minimum and maximum price using the price range selector. We can also show the products by filtering based on the selected minimum and maximum prices. In this tutorial, we will learn to create a price range selector using various libraries in ReactJS. Using the material UI to create a range selector The material UI provides various components we can import into the ...
Read MoreHow to create a Password Checklist in ReactJS?
Nowadays, applications use a one-time password or magic link for authentication, but we can’t ignore the authentication using the username and password. Whenever we allow users to register with a username and password, we should ensure that the password users have entered is strong. So, it can be unbreakable by hackers. In this tutorial, we will learn to verify the security level of the password in ReactJS. Create a Custom Validation Algorithm We can create a custom validation algorithm to check if the password is strong or weak. We can create regular expressions for lowercase, uppercase, and numeric ...
Read MoreGolang Program to Show Usage of Static keyword in Class
What is Static Keyword in Golang? The term "static" is used to describe variables, functions, and methods that have a fixed or unchanging value or behavior. In Go, the static keyword does not exist. In go we use the term "variables" to describe the memory locations where data is stored and manipulated. Static variables have a property of preserving their value even after they are out of their scope! Hence, static variables preserve their previous value in their previous scope and are not initialized again in the new scope. Algorithm Step 1 − First, we need to import ...
Read MoreGolang Program to Print Boundary Elements of a Matrix
What is Boundary Elements? In go programming language. the boundary elements of a matrix are the elements that are located on the outer edge of the matrix. They are located at four positions i.e the first row, the last row, the first column and at the last column. In a matrix of size m x n, the top boundary elements are the elements in the range matrix[0][0] to matrix[0][n-1], the bottom boundary elements are the elements in the range matrix[m-1][0] to matrix[m-1][n-1], the left boundary elements are the elements in the range matrix[0][0] to matrix[m-1][0], and the right boundary elements ...
Read MoreGolang Program to Sort the 2D Array Across Columns
What is 2D array in Golang? In Go programming language, a 2D array is an array of arrays, where each element of the outer array is a simple array itself. The code to declare a 2d array of size 2 X 3 can be done by writing var array [2][3]. It's important to note that 2D arrays have a fixed size, and once they are created, their size cannot be changed. If you need a dynamic 2D array, you can use a slice of slices. Here is an example of sorting a 2d array across columns − Input 3 2 1 6 4 5 ...
Read MoreGolang Program to Convert String to an Array
In Go Language, we have various data types to store data and the String data type is the one that is used to store a sequence of characters. The size of string variable is 1 or 8 bits. An array on the other hand is a data type that is used to store data at contiguous memory locations. Syntax func fields(s string) []string fields() function is present in strings package and is used to convert a string to an array of string. This function takes a string value as an argument and returns the corresponding array as the result. ...
Read MoreGolang Program to Show Usage of Access Modifier
In go programming language, there are two types of access modifiers i.e Exported and un-exported. Identifiers that are exported from the package in which they are specified are known as exported identifiers. They always begin with a capital letter. These are only valid in the package in which they are defined. Identifiers that are not exported from any package are referred to as un-exported identifiers that are written in lowercase. Syntax func len(v Type) int The len() function is used to get the length of a any parameter. It takes one parameter as the data type variable whose ...
Read MoreDifference Between GeForce 9800 GT and 9800 GTX
These two graphics cards are the most popular on the market. The GeForce 9800 GT is less powerful than the 9800 GTX but much less expensive. The 9800 GT graphic card consumes the very less power. The 9800 GTX, on the other hand, provides superior performance and is a better pick for gamers or anybody looking for the greatest gaming experience possible. Overall, both cards are excellent choices, but the 9800GTX is the superior option for individuals who need the best performance. Nvidia's GeForce graphics card family is one of its most enduring. Nvidia has developed several models with varying ...
Read MoreGolang Program to Convert String to Object
In Golang program, a string is a data type that contains literals and characters whereas an object is a data type created from classes by keeping similar types of properties together. In this article, we will look at two methods by which we can convert a string to an object in go programming language. Syntax func Split(str, sep string) []string Split() function is used to split a string through a provided separator. This function is present in strings package and it accepts the string to split as an argument along with a separator. The function then returns the final ...
