Recursion: Length of a String

[danielpaul]

Write a function that returns the length of a string. Make your function recursive.

Examples

length("apple") ➞ 5

length("make") ➞ 4

length("a") ➞ 1

length("") ➞ 0

Notes Check the Resources tab for info on recursion.

have a look at the differences between iterative methods and recursive methods. https://medium.com/backticks-tildes/iteration-vs-recursion-c2017a483890
