Haskell Program to Iterate over enum
In Haskell, an enumeration (or "enum") is a type that has a finite set of values. The values are called constructors, and are usually defined using the data keyword. Here's an example of an enumeration type that represents the four seasons − data Season = Spring | Summer | Fall | Winter Enumerations are used to represent things like states, modes, or options that have a fixed set of possible values. Method 1: Iterate over enumeration type This method is used to directly iterate over the enumeration type in Haskell. Here, we define the list of all the enumeration ...
Read MoreHaskell Program to Implement multiple inheritance
Haskell is a functional programming language and does not have a concept of inheritance. Instead, it uses type classes to achieve similar functionality. This tutorial will help us in implementing the same in Haskell. Method 1: Implement a type class that simulates multiple inheritances. This method uses type class to simulate the multiple inheritance. Here, we define two parent class and one child class. And the function of child class is being called. Once the function is being called it will take instance from both the parent class and the final output is displayed. Algorithm Step 1 − The ...
Read MoreHaskell Program to initialize and print a complex number
This tutorial will help us in initializing and printing a complex number. In Haskell, the Data.Complex library provides a Complex type to represent complex numbers. Method 1: Using Complex data type This method defines a Complex data type that holds the real and imaginary parts of a complex number, and an instance of the Show type class for Complex, which allows it to be printed using the putStrLn function. In the main function, it creates a complex number object with real part and imaginary part. Then it prints the complex number using the putStrLn function and the show function. Algorithm ...
Read MoreGet the Triplets in an Array Whose Sum is Equal to a Specific Number in Java
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to get all the triplets in the array whose sum is equal to a specific number. Here triplets refer to any three elements of the array which meet a specific condition. Note − The array must be an integer array. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {3, 4, 25, 6, 13, 9}. ...
Read MoreSwift Program to find the prime numbers from the array
In this article, we will learn how to write a swift program to find the prime numbers from the array. Prime numbers are those numbers that are only divisible by 1 and itself. Or we can say prime number have only two factors that are 1 and the number itself. For example, 1, 2, 7, 3, 11, 31, etc. So to find the prime numbers from the given array, we individually check each element of the given array is prime or not. Algorithm Step 1 − Create a function. Step 2 − Check if the number is greater than ...
Read MoreSwift Program to remove all 'nil' elements from the array
In this article, we will learn how to write a swift program to remove all ‘nil’ elements from the array. Till now we all know that an array can store elements of a single data type. But Swift array can also hold elements of multiple data types. To store multiple data types in the array we use [Any], where [Any] specifies that the address can hold elements of any data types. Similarly an array also contain nil value. Here we use the following methods to remove nil elements from the array. Using compactMap() function Using filter() function ...
Read MoreSwift Program to find the EVEN numbers from the array
In this article, we will learn how to write a swift program to find even numbers from the array. Even number are those number which are completely divisible by 2. For example, 2, 6, 50, 20, etc. Here we use the following methods to find the even numbers from the array. Using for-in loop Using filter() function Method 1: Using for-in loop To find the even numbers from the given array we use for-in loop. Using for-in loop we iterate through each element of the given array and check if the element is even number or not. ...
Read MoreSwift Program to fetch elements from an array based on an index
In this article, we will learn how to write a swift program to fetch elements from an array based on an index. Using array syntax 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. In an array, every element has an index. The array index is start from 0 and goes up to N-1. Here N represent the total number of array elements. To retrieve elements from the array according to their index we can use subscript syntax. ...
Read MoreSwift Program to Convert Set of String to Array of String
In this article, we will learn how to write a swift program to convert set of string to array of string. 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. Now to convert a set of string to an array of string we use the following two methods − Using Array() initializer Using map() function Method 1: Using Array() Initializer To convert a set of string to an array of string we can use Array() initializer. ...
Read MoreGolang program to search an element in the slice
In this tutorial, we will grasp how to search an element in slice using different set of examples. A slice is a sequence of elements just like an array. An array is a fixed sequence of elements whereas slice is a dynamic array which means 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. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used to add values to an array slice. It takes number of arguments. The first argument ...
