In swift, a set is used to create an unordered collection of unique elements. In Swift, to store a nil value in the set you need to define the set as a optional type because nil is a optional value. So to remove null for a set we can use inbuilt functions like remove() and filter(). Lets discuss both the methods in detail along with examples. Method 1: Using remove(_:) Function The remove(_:) function is used to remove or delete a specified element from the given set. Syntax func remove(ele) Where ele is the element which we want to ...

In Swift, a set is used to create an unordered collection of unique elements. To remove a subset from a set Swift provide two insult functions named as subtract() and subtracting(). Lets discuss both the methods in detail along with examples. Method 1: Using subtract(_:) Function The subtract(_:) function is used to remove the given subset from the specified set. Syntax func subtract(_subset:mSet) Where mSet is the subset which we want to remove from the given set and it must be a finite set. This function return a set after removing the common elements of set and subset. Example ... Read More
In Swift, linear search is the most easiest search algorithm. It is also known as sequential search because it check all the elements of the given array or sequence one by one. If the target element is found, then return the index of that array otherwise return element not found. So lets check if the given array contains the target element or not using recursive linear search. Algorithm Step 1 − Create a function to check if the given element is present in the specified array or not using recursive linear search. Step 2 − Inside the function, we ... Read More
Just like other programming languages Swift also supported two- dimensional array. A two dimensional array is known as an array of array that store same type of data in a tabular format. Or we can say 2-D array is an array which represent homogeneous data in rows and columns. Syntax var twoDArray:[[Int]] = [[2, 3], [3, 4]] To read two-dimensional array from the user Swift provide an inbuilt function named as readLine(). The readLine() function read a string of characters from the input. If the EOF has already been reached when this function is called, then it will ... Read More
This article discusses how to remove null values from a Python list. Before proceeding, it is necessary to understand what a null value is? What a List is? Why it is necessary to remove null value from list. Let’s move ahead with the topic and understand them in detail. Let’s start with the Null value. Null Value is defined as a parameter that does not have a value. It indicates the absence of a value. Python has a special value for "Null" that shows a variable doesn't point to anything. But in Python there is no null, there ... Read More
Python is an interpreted, object–oriented, high level, programming language with dynamic semantics. Developed by Gudio Van Rossum in 1991. It supports multiple programming paradigms, including structured, object-oriented and functional programming. What Is A Set? Set is an unordered collection data type that iterable, mutable and has no duplicate element. Set is represented by {}. Set is highly optimized method for checking whether a specific element is present in the set. Sets are created by placing all the items or elements inside curly brackets {}, separated by comma, or by using built in “set ()” function. It can have various ... Read More
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. To print a set we can use for-in loop, forEach() function, as well as the name of the set. Lets discuss all the methods one by one in detail along with examples. Method 1: Name of the Set To print a set we simply call the name of the set in the print() function. It will display set elements in the square bracket([]). Or we can say that ... Read More
Before we are going to learn about how to get substring between two similar characters in JavaScript. Let’s have a quick view on the characters in JavaScript. In a string, the charAt() method returns the character that is located at the given index (position). First character's index is 0, second character's index is 1. Getting substring in JavaScript The substring() method takes a string and extracts all characters between two indices (positions), then it returns the substring. Characters are taken out of a string using the substring() technique. The initial string is left alone when using the substring() technique. Syntax ... Read More
In JavaScript Arrays are used to hold several values in a single variable. When opposed to a variable, which can hold only one value, this Each element of an array has a number associated with it called a numeric index that enables access to it. Arrays in JavaScript begin at index zero and can be modified using a number of different techniques. Let's take a look at the general case of sorting an array that contains undefined in JavaScript. The array is given below − var namearr = ["Zebra", "Yatch", undefined, "Egg", undefined]; For sorting the array that was ... Read More
The most practical way to display datetime for efficient time analysis is in a 12 hour am/pm format. Additionally, this method clarifies the distinction between morning and evening. As an illustration, "am/pm" both specify a certain time period and make it simple to understand the time, which is not the case with the 24-hour format. This article will explain the ways of displaying JavaScript datetime in 12hour am/pm format. Displaying JavaScript datetime in 12hour am/pm format Let’s dive one by one to understand more about displaying JavaScript datetime in 12hoyur am/pm format. We can extract the hours and minutes from ... Read More
