Welcome to a new and interesting enough programming tutorial! Swift is a rich-featured language and it couldn’t be missing a great feature such as thehigher order functions. According toWikipedia: In mathematics and computer science, a higher-order function is a function that does at least one...

If there is one downside in higher order functions, then that is the bit unusual way to write them comparing to other more “Swifty” code. But being uncomfortable with them is not a reason for not making your life easier. It’s all just a matter of habit and training. If higher orde...
you will learn about the reduce code using Higher order functions like Map, Filter, Reduce, flatMap, etc… In Swift, you can use Map, Reduce and Filter to loop over collection types like array and dictionary without using a for loop. Here are some examples of the Array Functions...
In order to make this an operation withO(1)complexity, we can transform thestudentsarray into a dictionary where the key is the student ID and the value is theStudentobject. For that, we will first leverage the array’smap(_:)function to transform the array into an array of tuples with...
I want to get the pair of given sum by using higher order functions. I am able to do this using iterative approach. Can someone help me to solve the problem using higher order function. let array = [1,2,3,4] let givenSum = 5 for i in 0..<array.count { let j = i + 1 for...
higherOrderFunctions.swift /**For this code challenge, let’s define a math operation as a function thatcarries out some work on two integers and returns an integer as well. Anexample is the function below, `differenceBetweenNumbers`, which takes twointegers and calculates the difference between...
In continuation to our earlier studies related to energy loss and associated straggling for swift heavy ions which are generally considered as first and second order moments, respectively, in the present study, we have developed a method for the determination of skewness (third-order moment) in ...
Learn about Higher Order Components (HOCs) in React JS, a powerful pattern for reusing component logic and enhancing the functionality of components.
After a Texas man smashed a $4,000 Taylor Swift-themed guitar with a hammer and the video went viral, the destroyed instrument is back on eBay - and it's fetching an even higher price.
