The main objective for the problem statement is to perform a circular shift on the strings in Javascript. The circular shifts can be left shirt or right shift. And implement this solution in Javascript. Understanding the Problem The problem at hand is to shift the strings circularly left and right with the help of Javascript functionalities. Circular shifting means we have to move the characters of the given string in a circular manner in which the characters that are to be shifted beyond the boundaries of the string and it should reappear at the opposite end. ...

In the given problem we are required to retrieve the key and values from an object in an array with the help of Javascript. So here we will retrieve the keys and values from an object in an array with the help of two methods provided by the object class in Javascript. Understanding the Problem Statement The problem statement is to retrieve the keys and values from a given object in an array with the help of Javascript. So in Javascript the object is a collection of properties in which every property is a key and value pair. ... Read More
In this article, we will learn the difference between default exports and named exports in javascript, and how we can use them to effectively organize our code structure. In javascript, we can use default exports and named exports so as to have separate files or modules for separate pieces of code. This helps in enhancing code readability and tree shaking to a great extent. Default exports Named exports A default export allows us to export a single value or function as the default export of a module. A named export allows us to export multiple values ... Read More
In the given problem statement we are presented with a singly linked list and our task is to remove one element from the list. So we will discuss this operation step by step below. What is a singly Linked List ? A singly linked list consists of a series of nodes. It is a type of data structure. In this every node contains a value or we can say data and the list to the next node in the sequence. The first node in the list is called the head and the last node in the list points ... Read More
In this problem statement our aim is to write an algorithm to remove duplicate items from an array with a function with the help of Javascript functionalities. Understanding the problem statement In the above problem statement we have to create a function by which we can accept an array as a parameter and give a new array to store the unique items from the given input array and without including the identical values. For example - suppose we have an array as [0, 0, 2, 2, 3, 3] so after removing the duplicate numbers we will have ... Read More
Maven is a project management and comprehension tool that provides a complete build lifecycle framework. User can automate the project's build infrastructure in almost no time as Maven uses a standard directory layout and a default build lifecycle. In case of multiple environment, Maven can set-up the way to work as per standards in a very short time. As most of the project setups are simple and reusable, Maven makes life easy while creating reports, checks, build and testing automation setups. Maven provides developers ways to manage the following − Builds Documentation Reporting Dependencies SCMs Releases Distribution Mailing list ... Read More
testng.xml has a format as where we define what all test classes should be executed. There is no any specific way to provide regular expression in a class in . But there are work arounds those are useful to run specific @Test from a class. TestNG supports regular expression at include, exclude and package tags. Following are few ways those are handy to use regular expression in a test class run from a test suite. Mention all class names inside . And, inside the class use and . It will exclude all tests starting with name ... Read More
The indexing is the specific position of the element from the list. The unequal elements of two lists refer to those indexes whose elements are not matched from both lists. In Python, we have some built-in functions like enumerate(), zip(), filter(), etc. that can be used to filter unequal elements of two lists corresponding same index. Let’s take an example of this Given list, lst_1 = [10, 20, 30, 40, 50] lst_2 = [1, 20, 3, 40, 50] Then the final result becomes [20, 40, 50] these elements from the list matches the corresponding same index. Syntax The following syntax ... Read More
The name Numpy stands for Numerical Python. It helps to solve the mathematical operation on an array. In Python, we have some built-in functions such as nditor(), T(), array(), shape[], and apply_along_axis() that will be used to iterate over columns in Numpy. Syntax The following syntax is used in the examples- nditer() The NumPy module contains this built-in function for iterator objects. T() This function refers to transposing of the index in a column dataframe. array() This is a built-in function in Python that creates the array. An array is defined by collecting the items of ...

The reverse slice is defined by creating a slice that begins with the length of the string and ends with the 0th index. For reversing the list element it will use the negative value notation, where we can get a reversed order of the original list element. In Python, we have some built-in functions such as append(), len(), and, range() will be used to solve the K elements Reversed Slice. Syntax The following syntax is used in the examples- append() This built-in method in Python can be used to add the element at the end of the list. len() ... Read More
