An ALGORITHM is:

• An error in a program.
• A list of steps you can follow to finish a task.
• Trying again and again, even when something is very hard.
• A placeholder for a piece of info that can change.

A program is:

• an algorithm that has been coded into something that can be run by a machine.
• doing something over and over again.
• a piece of code you can call over and over again.
• finding and fixing errors in a program.

In coding, an event is:

• trying again and again, even when something is hard.
• an example of being a good digital citizen.
• an error in a program that prevents the program from running as expected.
• an action that causes something to happen.

In coding, a LOOP is:

• an error in a program.
• a statement that only runs under certain conditions.
• doing something over and over again.
• a placeholder for a piece of information.

PERSISTENCE is:

• part of being a good digital citizen.
• trying again and again, even when something is very hard.
• an action that causes something to happen.
• a list of steps you can follow to finish a task.
