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
Python refers to the high-level programming language that has various tools and built-in functions to analyze text data. This problem statement is a common task that uses some built-in functions- filter(), isdigit(), isalpha(), findall(), split(), and, append() to find the both alphabet and numbers using Python. Let’s see how to take the input of the program to get the result: Input my_text = "WELCOME TO CLUB100" Output CLUB100 Syntax The following syntax is used in the examples- filter() The filter() method is applied when it filter the items based on specific conditions. In simple terms, it allows ... Read More
The tuple list defines the two different datatypes of Python that represent the static and dynamic characteristics respectively. In a dictionary, we can create keys using tuples whereas lists cannot be used as keys. In Python, we have some built-in functions like next(), items(), index(), lambda, and, min() will be used to Find the first element by the second in the tuple list. This type of circumstance occurs when the second element holds the important information as a key for identifying the desired tuple. Let’s take an example of this: The given tuple list, my_tup = [("India", 35), ("Indonesia", 12), ... Read More
The dictionary is one of the most popular among four datatypes known for unordered collection of key-value pairs. The Python matrix will be used to represent the list of lists whereas an inner list represents the row-value of a matrix. A coordinate dictionary is defined as tuples to set the rows and columns by giving coordinates value. In Python, we have some built-in functions such as len(), range(), zip(), etc. that can be used to solve Convert Matrix to Coordinate dictionary. Syntax The following syntax is used in the examples- len() The len() is a built-in method in Python ... Read More
Promises, in JavaScript, can be used to simplify asynchronous programming, making it easier to handle asynchronous operations like I/O operations or communicate with an external system or machine. Promises are objects that represent the eventual completion or failure of an asynchronous operation and its resulting value. They provide an easy way to deal with asynchronous code, allowing us to write cleaner and more readable code. Here we will discover what are promises in javascript and how to use them to incorporate asynchronous programming behaviour into our control flow, in this tutorial. A promise has 3 states − Pending − ... Read More
