Swift Program to Check if a Set is empty
In Swift, a set is used to create a collection of unique elements. In a set, the elements are not arranged in a particular order. Now to check if a set is empty or not Swift provide an inbuilt property named as isEmpty. This property will return true if the given set is empty. Otherwise it will return false. Syntax newSet.isEmpty Where newSet is the name of the set and we can access the isEmpty property using the dot operator. This property's return type is bool, meaning if it returns true, it means the set is empty. If it ...
Read MoreSwift Program to Convert an Set of String to Comma Separated String
Swift provide a inbuilt method named as joined() to convert a set of string to comma separated string. This function return the concatenated elements of the given sequence by inserting the given separator in between each element of the sequence. Syntax func joined(separator: sep) Where the separator parameter contains a string or sequence, which is further used to insert between each element of the given sequence. This function returns a concatenated or joined sequence of elements. Example In the following code, we will create and initialize a set of strings. Then we join the elements of the set ...
Read MoreSwift Program to Add Two Complex Numbers by Passing Class to a Function
In swift, a complex number is the combination of real and imaginary number. So we create a class to store the real and imaginary part of the complex number and then we pass this class in the function to find the sum of two complex numbers. Algorithm Step 1 − Create a class to store the real and imaginary part of the complex number. Step 2 − Create a function named as ‘add’ which takes two class objects as a parameters and return the sum of the two complex numbers by adding the real and imaginary part ...
Read MoreSwift Program to print the right diagonal matrix
A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. So here we print the right diagonal of square matrix. Square matrix is a matrix in which the number of rows and columns are same. For example 3x3, 5x5, 7x7, etc. In this article, we will learn how to write a swift program to print the right diagonal matrix. Algorithm Step 1 − Create a function. Step 2 − Run for-in loop to iterate through each element of the matrix. Step 3 − Check for ...
Read MoreSwift Program to print the left diagonal matrix
In this article, we will learn how to write a swift program to print the left diagonal matrix. A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. So here we print the left diagonal of square matrix. Square matrix is a matrix in which the number of rows and columns are same. For example 3x3, 5x5, 7x7, etc. Algorithm Step 1 − Create a function. Step 2 − Run for-in loop to iterate through each element of the matrix. Step 3 − Check ...
Read MoreSwift Program to Check whether a number is a Perfect Cube or not
A number is a perfect cube if the result of the three time multiplication of a whole number is the number itself. For example: number 5 is a per Number = 125 125 = 5*5*5 Here 125 is a perfect cube. Number = 98 Here 98 is not a perfect cube. In this article, we will learn how to write a swift program to check whether a number is a perfect cube or not. Method 1: Using user defined function To check if the given number is a perfect cube or not, we create a function that check each number ...
Read MoreSwift Program to Check if the given number is Perfect number or not
A perfect number is a positive number that is equal to the sum of its factors, excluding the number itself. For example − Number = 6 Proper divisors = 1, 2, 3 Hence, 6 is the perfect number because the sum of its divisors is 6(1+2+3) Number = 10 Proper divisors = 1, 2, 5 Hence, 10 is not a perfect number because the sum of its divisors is 8(1+2+5) In this article, we will learn how to write a swift program to check if the given number is a perfect number or not. Algorithm Step 1 − Create ...
Read MoreSwift Program to calculate the sum of rows of matrix elements
A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc.In this article, we will learn how to write a swift program to calculate the sum of rows of matrix elements. Here we are using the following methods to find the sum of the rows elements − Using nested for-in loop Using in-built function Method 1: Using nested for-in loop Here we use nested for-in loop to find the sum of rows of matrix elements. Algorithm Step 1 − Create a function. Step 2 ...
Read MoreSwift Program to Calculate the Sum of Matrix Elements
A matrix is a rectangular array of numbers. Or we can say that a matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. In this article, we will learn how to write a swift program to calculate the sum of matrix elements. So here, using the following methods we calculate the sum of matrix elements. Sum of square matrix elements Sum of any matrix elements For example, we have the following matrix − $\mathrm{Matrix\:=\:\begin{bmatrix}1 & 4 & 5 & 6ewline4 & 7 ...
Read MoreSwift Program to calculate the sum of columns of matrix elements
A matrix is an arrangement of numbers in rows and columns. The matrix can be of various types like square, horizontal, vertical, etc. In this article, we will learn how to write a swift program to calculate the sum of columns of matrix elements. Here we are using the following methods to find the sum of the column’s elements − Using a nested for-in loop Using in-built function Method 1: Using nested for-in loop Here we use a nested for-in loop to find the sum of columns of matrix elements. Algorithm Step 1 − Create a function. Step ...
