In the given problem statement we are asked to find out long factorials of a Bigint value with the help of javascript functionalities. BigInt is a data type in javascript, which is used to calculate the factorial of a large number. What is the BigInt data type in JavaScript ? Let's understand the working of a BigInt data type in JavaScript. In Javascript, there are so many data types available to define the data, one of them is BigInt. BigInt is a built−in data type in Javascript which represents integers of large size. It was introduced in ECMAScript 2020. It ... Read More
The list in python is a collection of similar items. We may at times need to compare data items in the two lists to perform certain operations. We will discuss certain methods to compare two lists in python.Using list.sort() and == operatorThe list.sort() method sorts the two lists and the == operator compares the two lists item by item which means they have equal data items at equal positions. This checks if the list contains equal data item values but it does not take into account the order of elements in the list. This means that the list [1, 2, ... Read More
Introduction Java supports eight types of operators; the “!” operator is one of them. In Java, an operator is a symbol used to execute operations. Operators are entities that can modify the values of operands. Java makes authoring, compiling, and debugging code simple. It is helpful in creating code that can be reused and applications that are modular. It was created with the goal of having a few implementation dependencies as feasible. Let’s discuss in detail about the Java operators, “!” operator and where to use it with some working examples. Java operators Operators in Java are symbols that are ... Read More
Introduction In real life, we can call tables, chairs, lamps, etc. objects as they have some attributes and functions. We can say that anything that has attributes or properties and some functionality like a lamp has a stand and a bulb and it can light up a room so it is an object. In Java also, we have objects and they have their own properties. Objects are basically the instance of the class and the class provides a blueprint for the creation of an object. Let’s have a brief discussion on objects and how to create an object in Java. ... Read More
In the given problem statement we are asked to truncate a string with the help of javascript functionalities. We can solve this problem with the help of Javascript’s built−in functions slice() and substr(). What do you mean by truncating a string ? Let's understand the meaning of truncating a string. Truncating a string means cutting the length of a string by removing character from the beginning, end or middle part of the input string. The aim of truncating a string is to make a certain space or to make it more readable by truncating unnecessary information from the input ... Read More
The Given problem is trying to find three strictly increasing numbers with consecutive or non−consecutive numbers in an array with the help of javascript. Understanding the Problem Before starting to write algorithms and programmes for the given problem first we will understand the logic behind the problem. Consider a set of array with some random numbers in it. So JavaScript allows us to loop through an array and maintain track of the smallest and second−smallest values in order to find three strictly rising numbers. In this algorithm, We will discover three strictly growing integers if a third value ... Read More
Python dictionaries are an unordered collection of key value pairs. In this tutorial we will see how we can add new key value pairs to an already defined dictionary. Below are the two approaches which we can use.Assigning a new key as subscriptWe add a new element to the dictionary by using a new key as a subscript and assigning it a value.ExampleCountryCodeDict = {"India": 91, "UK" : 44 , "USA" : 1} print(CountryCodeDict) CountryCodeDict["Spain"]= 34 print "After adding" print(CountryCodeDict)OutputRunning the above code gives us the following result −{'India': 91, 'USA': 1, 'UK': 44} After adding {'Spain': 34, 'India': 91, ...

In the given problem statement we are asked to sort an array including the elements present in the subarrays with the help of javascript functionalities. As we talk about sorting any list or array the sort() and flat method is useful. What are sort(), flat() and isArray() methods in JavaScript ? Let's understand the working of sort, flat and isArray methods in JavaScript. The sort() method is basically used to sort the elements of an array and returns the sorted array. The items are sorted in dictionary order by default. But we can provide a function as an argument to ... Read More
In this article, we will show you how to convert a python dictionary to a list. Below are the methods to accomplish this task: Using list & items() Method Using keys() Method Using values() Method Using List Comprehension Using Zip() Function Using map() Function Using for loop & items() Method Dictionaries are Python's version of an associative array data structure. A dictionary is a collection of key-value pairs. Each key pair is represented by a key pair and its associated value. A dictionary is defined by a list of key-value pairs enclosed in curly braces and ... Read More
In this article, we will show you the remove an element from a list by index using Python. Here we see 4 methods to accomplish this task − Using the del keyword to remove an element from the list Using the pop() function to remove an element from the list Using slicing to remove an element from the list Using indices to remove multiple elements from the list Assume we have taken a list containing some elements. We will remove a specific item from a list by giving the index value using the above-specified methods. Method 1: Using ... Read More
