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

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

Python is derived from many other languages including ABC, Modula-3, C, C++, Algol-68, SmallTalk, and UnixShell, and many other scripting languages. Now, as we know this article is all about converting a list of strings to comma-separated strings. Before diving deep into it, it’s necessary to know in detail about strings and lists in python. Let’s move ahead with the topic and understand them in detail. Starting off with string. What is a String? Python strings are sequences of characters, which means they are ordered collections of characters. "This is a string." 'This is also a string.' ... 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. List are mutable means that you can change the values of list, like we can add an element, remove, repeat and allows indexing and slicing like strings an element from a list by using different operators. List can be created by using square brackets. By placing elements inside square bracket[ ], separate by commas. For example: list1= [“a”, ”b”]. There is a one more type of list known ... 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

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 List in Python List is a data structure in python, which is changeable, mutable and iterable ordered sequence of element. They are used to store multiple elements in a single variable. List allows duplicate elements. Lists are mutable which means that you can change the values of list, we can add an element, remove, repeat and allows indexing and slicing like strings an element from a ... Read More

In Python, a single variable can contain multiple items by using lists. One of the four builtin data types for storing data collections in Python is a list; the other three are tuples, sets and dictionaries, each with its own purpose. What Is List? Square brackets are used to build lists.The most effective tool in Python is the list because they don't necessarily have to be homogeneous. DataTypes like Integers, Strings, and Objects can all be found in one list. Because lists are mutable, changes can be made to them even after they have been created. In this article, ... Read More

Python is an interpreted, object–oriented, high level, programming language with dynamic semantics. Developed by Gudio Van Rossum in 1991. List is a data structure in python, that is changeable, mutable and iterable ordered sequence of element. They are used to store multiple elements in a single variable. List can be created by using square brackets. By placing elements inside square bracket [], separated by commas. For example: list1= [“a”, ”b”]. There is a one more type of list known as “Nested list”. It is list within list. list1=[“a”, ”b”[1, 2]”c”] How To Get Minimum From List Let’s learn ... Read More
