Swift Program to check if a given string is Keyword or not
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 MoreSwift Program to check if an Array is Palindrome or not
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 MoreSwift Program to Convert Array to Set
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 MoreSwift Program to find the 1's complement of the given number
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 MoreSwift Program to find the given number is strong or not
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 MoreSwift Program to get array elements after N elements
An array is used to store elements of same data type in an order. So now we extract the array elements after N elements. For example − Array : [2, 4, 5, 6, 7, 9] N = 3 ResultArray = [6, 7, 9] In this article, we will learn how to write a swift program to get array elements after N elements. Algorithm Step 1 − Create function. Step 2 − Create a new array using Array() initializer that containing elements after N elements. Step 3 − Return the resultant array. Step 4 − Create an array and a ...
Read MoreSwift Program to Print object of a class
In this article, we will learn how to write a swift program to print object of a class. A class object is known as an instance of a class. For example, colour is a class then obj1, obj2, obj3 and obj4 are the objects from the class. A class can have multiple objects. Syntax var objectname = Classname() Here, using the above syntax we can create an object of a class. Algorithm Step 1 − Create a class with properties and a constructor. Step 2 − Create a function to print the object of the given class. Step ...
Read MoreSwift Program to fill an array with a specific element
In this article, we will learn how to write a swift program to fill an array with a specific element. 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. We can fill an array with a specified element using the following methods − Using user defined function Using ...
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 ...
