Mastering Variadic Functions in Go | Programming Tutorials

Introduction

In Go, a function that can take a variable number of arguments is called a variadic function. This challenge will test your understanding of how to use variadic functions in Go.

Variadic Functions

In this challenge, you need to implement a function named max that takes an arbitrary number of integers as arguments and returns the maximum value.

Requirements

The function max should take an arbitrary number of integers as arguments.
The function max should return the maximum value of the integers passed as arguments.

Example

$ go run variadic-functions.go
[1 2] 3
[1 2 3] 6
[1 2 3 4] 10

## Another key aspect of functions in Go is their ability
## to form closures, which we'll look at next.

Summary

In this challenge, you learned how to use variadic functions in Go. You implemented a function named max that takes an arbitrary number of integers as arguments and returns the maximum value.
