Swift Program to Sort the Elements of an Array in Ascending Order
In this article, we will learn how to write a swift program to sort the elements of an array in ascending order. Here we are going to use the following 2 methods: sort() function without parameter sort(by:) function with parameter To sort the elements of an array Swift provides an in-built function named sort(). This function can work with or without parameters. By default this function sort the array in ascending order. Otherwise, you can pass < in the by a parameter of the sort(by:) function to sort the array in ascending order. Method 1: sort() Function Without ...
Read MoreSwift Program to Remove All Occurrences of an Element in an Array
In this article, we will learn how to write a swift program to remove all occurrences of an element in an array. So here we use the following methods − Using an inbuilt function Without using an inbuilt function Method 1: Using the removeAll() Function To remove all the occurrences of an element in an array we use a pre-defined function named removeAll(where:). This function removes all the elements from the given sequence that satisfy the given condition. For Example − Array = [2, 3, 5, 67, 2, 87, 2, 68] Element = 2 Output array = [3, 5, 67, ...
Read MoreSwift Program to Print an Array
This article will teach us how to write a swift program to print an array. To print an array, we are using the following methods − Using array name Using for loop Using a while loop Using forEach() method Method 1: Print the array using the array name We can print an array by directly using the name of the array in the print function. Syntax Following is the syntax − print(arrayName) Here we simply pass the name of the array in the print function to display the array. Example The following Swift program shows how to print ...
Read MoreSwift Program to Find Common Array Elements
This article will teach us how to write a swift program to find common array elements. So here we use the following methods − Using the filter method Using sets But before moving to the methods, we first understand common elements with the help of an example. Suppose we have two arrays − Arr1 = [2, 4, 6, 89, 78] Arr2 = [56, 88, 32, 4, 99, 89] So the common elements between two arrays are [4, 89]. Because they are available in Arr1 and Arr2. Method 1: Using filter(_:) Method To find common elements between two arrays ...
Read MoreSwift Program to Count the elements of an Array
In this article, we will learn how to write a swift program to count the elements of an array. To count the elements of an array swift provide a count property. This property will return the total number of elements present in the specified array. For example − Arr = [3, 5, 6, 4, 6] so the count will return 5. Syntax var count: Int{get} Or you can also write it as − arrayName.count Here count is the property of the array to count the total elements present inside the array. To use this property we ...
Read MoreSwift Program to Check if Two Arrays Are Equal or Not
In this article, we will learn how to write a swift program to check whether two arrays are equal. To check if two arrays are equal to not either, we are going to use the following two methods − using == operator elementsEqual(_:) method. Both method and operator return true if both the given array has the same elements. Otherwise, they will return false. For example, arr1 = [2, 3, 4, 5] and arr2 = [2, 3, 4, 5] both arrays are equal so both the method and operator will return true. arr1 = [2, 3, 4, ...
Read MoreSwift program to print pascal's triangle
This tutorial will discuss how to write swift program to print Pascal’s triangle. A pascal’s triangle is a triangular array of the binary coefficient. It is a never ending equilateral triangle which always follows the rule of adding two numbers from the above row to get the number of below row. For example, the initial number of first row is 1 so the number of 2nd row is the sum of two numbers of the 1st row that are 0+1 and 1+0, so we get [1, 1]. Now the number of 3rd rows is the sum of the two numbers ...
Read MoreSwift program to check whether a number can be expressed as sum of two prime numbers
This tutorial will discuss how to write swift program to check whether a number can be expressed as a sum of two prime numbers. Prime numbers are those numbers that are greater than 1 and has exactly two factors that is 1 and the number itself. For example, 7 is the prime number because it has only two factors that are 1 and 7. Here we check that the given number can be expressed as Sum of two prime numbers. For example − Number = 10 So 10 can be expressed as a sum of prime numbers − 3+7 ...
Read MoreSwift program to get the remainder of float numbers using library function
This tutorial will discuss how to write swift program to get the remainder of float numbers using library function. A number with fractional component is known as float numbers. For example, 34.5, 2.1, 0.2, etc. We can divide two float numbers with each other to find the remainder and quotient. Remainder is the value left after dividing a number by another number. Below is a demonstration of the same − Input Suppose our given input is − Num1 = 0.16 Num2 = 0.04 Output The desired output would be − Remainder = 0.0 To find the remainder of ...
Read MoreSwift program to print spiral pattern
This tutorial will discuss how to write swift program to print spiral pattern. Numeric pattern is a sequence of numbers which is used to develop different patterns or shapes like pyramid, rectangle, cross, etc. These numeric patterns are generally used to understand or practice the program flow controls, also they are good for logical thinking. To create a spiral pattern of numbers, we can use any of the following methods − Using nested for loop Using stride Function Below is a demonstration of the same − Input Suppose our given input is − Num = 6 Output ...
