Scala – Recursive Functions
In Scala, Recursion is an important concept in pure functional programming language.By definition, Recursive function is a function which calls itself. We need to to be careful while using recursive functions, because program may...
Scala Higher Order Function
In scala, when a function accepts another function as an argument or returns a function as an output, is called Higher order function. Let’s understand this with examples. Example1 Map is the good example...
