Day 1: Reverse a String

Learning Goals

• Practice algorithmic problem solving

Instructions

For this task, you'll need to write a method that reverses a string. Your method will receive one argument, a string, and be expected to output that string with its letters in reverse order.

Input: "hi"
Output: "ih"

Input: "catbaby"
Output: "ybabtac"

Do not call any type of built-in reverse method!

Please solve the problem using iteration.

Use the language of your choosing. We've included starter files for some languages where you can pseudocode, explain your solution and code.

Before you start coding

1. Rewrite the problem in your own words
2. Validate that you understand the problem
3. Write your own test cases
4. Pseudocode
5. Code!

And remember, don't run our tests until you've passed your own!
