In JavaScript, functions can be assigned to any variables, they can be passed as arguments to other functions, and can even be returned from other functions. This behavior of functions allow us create HOCs in javascript, which are functions that return other functions. These higher−order functions can be used in various applications like callback functions, function memoization, or transformation, etc. In this article, we will learn functions returning another function, aka higher−order functions in javascript, and how we use them to implement certain javascript features like callbacks, array/object filtering and transformations, etc. Let’s look at some of the examples to ...

The suffix of keys is a group of letters that is mentioned at the end of the word. In this problem statement, we need to create the specific variable that set the suffix key to filter the result by using some specific conditions. In Python, we have some built-in functions such as endswith(), filter(), lambda, append(), and, items() that will be used to Find Keys with specific suffix in Dictionary. Let’s take an example of this. The given dictionary, my_dict = {'compiler': 100, 'interpreter': 200, 'cooperative': 300, 'cloudbox': 400, 'database': 500} The suffix key is set to er, ... Read More
In Alphabetical series there are consists of 26 characters of which 5 characters are vowels such as a, e, i, o, u and the rest are called as consonants. In C++, we have predefined functions such as tolower() and length() that will help to Check whether all the substrings have number of vowels atleast as that of consonants. Let’s take an example of this. The string has only one consonant with the rest vowel “aiteau”. Hence, it is accepted as the final result. The string has more than one consonant with the rest vowel “appioa”. Hence, it is not ... Read More
The tuple is ordered or a finite sequence to collect the data. It can be represented by using parenthesis i.e. (). A byte integer is a simple number without having decimal or fractional values. In Python, we have some built-in functions such as from_bytes(), bytes(), unpack(), and, enumerate() will be used to Interconvert Tuple to Byte Integer. Syntax The following syntax is used in the examples from_bytes() The from_bytes() is an in-built function in Python that accepts two specific parameters bytes()- The bytes() is also a built-in function that defines the immutable series of integers. byteorder- The byteorder ...

This tutorial will teach you how to eliminate duplicate values from an array of items in Javascript by converting an array to a set. When storing distinct values from a collection of data in javascript, we can utilise the Set data structure to get rid of duplicate values. When we wish to eliminate duplicates from our data or take advantage of the special features offered by Sets data structure, converting an array to a Set can be helpful. Let’s look at some of the examples and methods to understand the concept better − Example 1 - Using the Set Constructor ... Read More
The Index match element Product refers to two different lists where it contains the elements and set to respective variable. If common matches are found, then it filters the element by multiplication. To solve this problem statement, Python has some built-in functions such as range(), len(), zip(), prod(), reduce(), and, lambda(). Let’s take an example of this. The given input lists: list_1 = [10, 20, 30, 40] list_2 = [10, 29, 30, 10] So, the common matches found in indexes 0 and 2 and its product become 10*30 = 300. Syntax The following syntax is used in the examples ... Read More
The atmost K element is set to a specific value in the given list to filter those indices whose elements are greater than the K value. In Python, we have some built-in functions such as enumerate(), range(), len(), where(), map(), range(), and, filter() that will be used to solve the Indices of atmost K elements in list. Let’s take an example of this. The given list, [10, 8, 13, 29, 7, 40, 91] and the K value set to 13. Now, it will check how many elements are less than or equal to 12 and filter those indices which are ... Read More
The frequency of elements consists of two different lists where one list defines the unique element and the other list defines the number of repetitions of the same element w.r.t to the first list. Then use some conditions and operations in the dictionary to set each element of the first list represented by a key whereas the value pair will be represented by counting the total number of repetitions of key element in the second list. In Python, we have some built-in functions such as Counter(), count(), defaultdict(), and, unique() will be used to solve the Frequency of elements from ... Read More
The K difference is set to any value that will be used to set the difference between two numbers. The consecutive element is those elements that follow the sequential order. In Python, we have some built-in functions such as range(), len(), abs(), append(), and, sort() will be used to solve the K difference Consecutive element. Let’s take an example of this. The given list, [5, 6, 3, 2, 4, 3, 4] The K value set to 1 means each consecutive elements follow the differences of 5. Then the final result becomes, [True, False, True, False, True, True] Explanation: The outcome ... 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. To summarize, Maven simplifies and standardizes the project build process. It handles compilation, distribution, documentation, team collaboration and other tasks seamlessly. Maven increases reusability and takes care of most of the build related tasks. TestNG and Junit are testing framework and can use Maven as build tool. It helps to maintain dependencies and their version at one place in pom.xml User can ... Read More
