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 More

An array is used to store elements of the same data type in order. Here we will learn how to write a swift program to find the index of the first occurrence of the specified item in the array. To achieve that we are going to use the following methods to find the index of the first occurrence of the array element − Using user-defined function Using firstIndex() function Method 1: Using user-defined function To find the index of the first occurrence of the specified element in the array we create a function which iterate through each elements ...

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 More

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 More

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 More

Heterogram string is a string in which no alphabet occurs more than once. For example, “Sky with cloud” is a heterogram because in the string each alphabet occurred only once. Whereas “colorful balloons” is not a Heterogram because in the string some alphabet like o, u, l, etc appears more than once. Here we will execute different examples that will check whether the given string is heterogram or not using swift programming language. Algorithm Step 1 − Create a function. Step 2 − Remove the white space from the string. Step 3 − Create a separate array to ... Read More

Pangram string is a string that contains all the English alphabet. For example − String = “The quick brown fox jumps over the lazy dog” Here the string is a pangram string which contains all the alphabetical characters from a to z in it. String = “ Hello! Swati how are you?” Here the string is not a pangram string because it does not contain all the 26 alphabetical characters from a to z. In this article, we will learn how to write a swift program to check if a string is pangram or not. So to check if the ... Read More

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 More

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 More

What is CHECKSUM? In computing, a checksum is a small-sized data created from a larger data set using an algorithm, with the intention that any changes made to the larger data set will result in a different checksum. Checksums are commonly used to verify the integrity of data that has been transmitted or stored, as errors or modifications in the data can cause the checksum to change. They can also be used to verify the authenticity of the data, as the checksum is often generated using a secret key known only to the sender and receiver. Why we use CHECKSUM? ... Read More
