To create a good algorithm, follow these simple steps:

1. Understand the Problem: First, figure out what you need to solve. For example, if you want to find the biggest number in a list, make sure you know how the list is organized. Is it sorted? Does it have repeating numbers?

2. Break It Down: Split the problem into smaller parts that are easier to handle. If you're looking for the biggest number, think about how you can compare each number in the list to find the biggest one.

3. Develop the Steps: Write down the steps you need to take to solve each part. For finding the biggest number, you can start with the first number and then see if the others are bigger.

   • Here are the steps to follow:
     • Start with the first number as your biggest number.
     • Go through the other numbers one by one.
     • If you find a number that's bigger, change the biggest number to this new one.

4. Test Your Algorithm: Lastly, check your algorithm using different examples. Try it out with various numbers, like negative numbers or a list with just one number, to make sure it works all the time.

By following these steps, you'll be on your way to creating great algorithms!
