Swift Program to Show Usage of Static keyword in Class
In Swift, static keyword is used to define or create type-level properties and method that only belongs to the class itself rather than to its instances. Or we can say that we can directly access the static properties and methods of a class with help of class itself instead of creating the instance of the class. Algorithm Step 1 − Create a class. Step 2 − Inside the class define static property using static keyword and a instance property. Step 3 − Also define a static method using and static keyword and a instance method. Step 4 − Outside ...
Read MoreSwift Program to Search an Element in a Set
In Swift, to search elements in a set we can use either contains(_:) function or linear search. Both the methods efficiently search an element in a set. Lets discuss both the methods in detail along with examples. Method 1: Using contains(_:) Function Swift provide an inbuilt function named as contains() function to search an element in a set. This function return true if the specified element is present in the given set. This function will return false if the specified element is present in the given set. Syntax sets.contains(myElement) Where sets is a finite set and myElement represent the ...
Read MoreSwift Program to Rotate Elements of an Array
In Swift, we create a user defined function to rotate the elements of an array. In this function, first we find the total number of rotation and then rotate the array by the specified number of rotation. For example − Array = [3, 5, 2, 1, 7, 9] Rotation = 2 Resultant Array = [2, 1, 7, 9, 3, 5] Algorithm Step 1 − Create a function that rotate the elements of the array in the specified number of rotation. Step 2 − Inside the function first we find the required number of rotations. Step 3 − Then ...
Read MoreSwift Program to Reverse a Set
In swift, a set is a unordered collection that only contain unique values. As we known that a set is an unordered collection so their is no direct way like an array to reverse the elements of the set. However you can reverse a set by converting it into an array and then apply reversed() method or any user defined function. And then convert back the result into set. Let discuss this method with the help of examples. Example 1 In the following example, we will have a set of string type. Now we convert it into array to ...
Read MoreSwift Program to Merge Two Sets
Merging two sets means combining all the elements of a set into another set without any duplicates. In Swift, we can either use formUnion() function or for-in loop to merge the elements of two sets. Lets discuss both the methods in detail along with examples. Method 1: Using formUnion() Function To merge two sets we can use formUnion() function. The formUnion() function is used to insert the elements of the given sequence into the set. Here the sequence can be anything a set, array, etc. This function merge two sets without any duplicates. Syntax set1.formUnion(set2) Where set1 and set2 ...
Read MoreSwift Program to Initializing a Set
In Swift, a set is used to define a collection of unique elements, means a set doesn’t contains duplicate elements. In a set, the elements are not arranged in a particular order. Initialising a set means to store some information in the set. It can be done at the time of declaration or after declaration. We can initialise a set in various way like initialising a set without explicitly passing data types, initialising a set with explicitly passing data types, and using inbuilt insert() function. Now lets discuss all the method in detail along with examples. Method 1 In this ...
Read MoreSwift Program to Implement Linear Search Algorithm
In Swift, the Linear search algorithm is the easiest search algorithm. In a linear search algorithm, searching starts from index 0 and checks all the elements of the given array/sequence one by one until the desired element is found. If the desired element is found, then return the index of that element. If the desired element is not found, then return null. For example − We have an element M = 13, now we search M in the following array using a linear search algorithm − The linear search algorithm starts from index 0 and compares M=13 with ...
Read MoreCreating a Dataframe from Pandas series
In data science, data is represented in various formats, such as tables, graphs, or any other types of structures. One of the most common data structures used to represent data is a DataFrame, which can be created using an array or a series. In this document, we will discuss how to create DataFrames from a Pandas Series object. Importance of Dataframe in data science! Dataframe is a two-dimensional table-like data structure that is widely used in data science. It is a very important tool for data manipulation, data analysis, and data visualization. Here are some of the key advantages of ...
Read MoreGolang Program to Use Field Tags in the Definition of Struct Type
In Go programming language, field tags are metadata that can be attached to the fields of a struct type. These tags provide additional information about the field such as its name, data type, validation rules, etc. Field tags are used extensively in many Go libraries and frameworks, including database and web application frameworks. In this article, we will explore how to use field tags in the definition of a struct type in Go programming language. We will also discuss some common use cases of field tags and their benefits. What is a Struct Type in Go? A struct type is ...
Read MoreIsomorphism in N-ary Trees
Isomorphism is defined as two trees either having identical or mirror structures. In the case of mirror structure, the left node data will always match the right node. For example, we will take a number nearest to the mirror and see what its reverse would be, that is the real concept of isomorphism. In this article, we are going to check whether two different binary trees are isomorphic or not. Let’s take an example of Isomorphism in N-ary Trees − Note that, L represents as left node whereas R represents as Right node Mirror structure of P and Q ...
