Recursion

The sum function takes an integer slice and returns the sum of all the integers in the slice. However, the function is incomplete and needs to be implemented using recursion.

Requirements

The sum function must be implemented using recursion.
The function must take an integer slice as input.
The function must return the sum of all the integers in the slice.

Example

$ go run recursion.go
5040
13

Summary

In this challenge, you were tasked with implementing the sum function using recursion. Recursion is a powerful tool that can simplify complex problems by breaking them down into smaller sub-problems. By completing this challenge, you should now have a better understanding of how to use recursion in Golang.
