Golang program to check if two slices are equal
In this article, we will see what are the ways to check whether two slices are equal or not with the help of relevant examples. A slice is a sequence of elements just like an array. An array is a fixed sequence of elements whereas a slice is a dynamic array, meaning its value is not fixed and can be changed. Slices are more efficient and faster than arrays moreover; they are passed by reference instead by value. Let us learn the concept through examples. Method 1: Using a built-in Function In this method, we will use reflect.DeepEqual() function from ...
Read MoreGolang program to count the elements of a slice
In this article, we will learn how to count the elements of a slice using a different set of examples. A slice is a sequence of elements just like an array. An array is a fixed sequence of elements whereas a slice is a dynamic array, meaning its value is not fixed and can be changed. Slices are more efficient and faster than arrays moreover; they are passed by reference instead by value. Let us learn through examples how it can be executed. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used to add values to ...
Read MoreGolang to remove null from a slice
In this article, we will learn how to remove a null value from a slice using a variety of examples. A slice is a sequence of elements just like an array. An array is a fixed sequence of elements whereas a slice is a dynamic array, meaning its value is not fixed and can be changed. Slices are more efficient and faster than arrays moreover; they are passed by reference instead of value. Let us learn through examples how it can be executed. Method 1: Using For Loop In this method, we will see how to remove a null value ...
Read MoreGolang program to print the left diagonal matrix
In this article, we will see how to print the left diagonal matrix with the help of suitable examples. A matrix is a 2-d array. Here in the examples, we will use a nested for loop which will iterate through the rows and columns of the matrix to print the left diagonal matrix. The output will be printed on the screen using fmt.println() function which is a print statement in Golang. Algorithm Step 1 − Create a package main and declare fmt(format package) package in the program where main produces executable codes and fmt helps in formatting input and ...
Read MoreGolang program to print right diagonal matrix
In this article, we will see how to print the right diagonal matrix with the help of suitable examples. A matrix is a 2-d array. Here in the examples, we will use a nested for loop which will iterate through the rows and columns of the matrix to print the right diagonal matrix. The output will be printed on the screen using fmt.println() function which is a print statement in Golang. Algorithm Step 1 − Create a package main and declare fmt(format package) package in the program where main produces executable codes and fmt helps in formatting input and ...
Read MoreHaskell Program to find the 1's complement of the given number
This tutorial will help us to find the 1's complement of the given number. The 1's complement of a binary number is found by inverting each bit of the number. A 1 becomes a 0, and a 0 becomes a 1. This is also known as the bitwise NOT operation. The 1's complement of a number can be useful in certain types of error-detecting and error-correcting Example:s, as well as in certain types of digital logic circuits. The most common use of 1's complement is in signed number representation where it's used to represent negative numbers. For example, if the ...
Read MoreHaskell Program to read the height of a person and the print person is taller, dwarf, or average height person
This tutorial will help us in reading the height of a person and printing if the person is taller, dwarf or average height person on being compared. The height value (in centimeters) is passed as argument to the function defined and then the height is being compared with the condition defined in Haskell. And the final output is displayed. Algorithm Step 1 − Program execution will be started from main function. The main() function has whole control of the program. Step 2 − Create user defined function to perform the task Step 3 − The if-else statement is defined ...
Read MoreHaskell Program to extract the last two digits from the given year
This tutorial will help us in extracting the last two digits from the given year. The year value is passed as an argument to the function defined and then the last two digits are extracted by using various methods in Haskell. And the final output is displayed. For example, For entered year = 2023, the last two digits = 23. Algorithm Step 1 − The Data.Char module is imported to use digitToInt function. Step 2 − The extractLastTwoDigits function is defined Step 3 − Program execution will be started from main function. The main() function has whole control of ...
Read MoreHaskell Program to read coordinate points and determine its quadrant
This tutorial will help us in reading the x and y coordinates and determine its quadrant. If both the coordinates are positive, the point lies in first quadrant; if x coordinate is positive and y coordinate is negative, the point lies in fourth quadrant ; if x coordinate is negative and y coordinate is positive, the point lies in second quadrant and if both the coordinates are negative, then point lies in third quadrant. Algorithm Step 1 − The quadrant function is defined using certain conditions on x and y coordinates. Step 2 − Program execution will be ...
Read MoreHaskell Program to calculate the volume and area of Sphere
This tutorial will help us in calculating the volume and area of Sphere. The volume of a sphere is a measure of the amount of space inside the sphere. And area involves the surface area of the sphere. Method 1: Using the User-defined Function In this method, we will see two examples where we have used user-defined function with different techniques. Algorithm Step 1 − The Text.Printf module is imported. Step 2 − The volume and area functions are defined on the basis of simple mathematical formula as volume r = (4.0 / 3.0) * pi * (r ^ ...
