Day 21: Generics

Objective

Today we’re discussing Generics; be aware that not all languages support this construct, so fewer languages are enabled for this challenge. Check out the Tutorial tab for learning materials and an instructional video!

Task

Write a single generic function named printArray; this function must take an array of generic elements as a parameter (the exception to this is C++, which takes a vector). The locked Solution class in your editor tests your function.

Note: You must use generics to solve this challenge. Do not write overloaded functions.

Input Format

The locked Solution class in your editor will pass different types of arrays to your printArray function.

Constraints

• You must have exactly function named printArray. 1

Output Format

Your printArray function should print each element of its generic array parameter on a new line.

/**
*
* What is the Generic?
* That is being able to create a component that can work over a variety of types rather than a single one.
* JavaScript is a dynamically typed language and it doesn't have any generics. So we can write a normal function or method.
* Also, you can write in languages like TypeScript, Java, C#.
* It's a creation code in C#
