Boolean
What is an algorithm?
A set of instructions used to solve a problem
What does an if statement do?
Runs code only if a condition is true
What is another name for a procedure?

What does / mean in pseudocode?
Division
What is a substring?
A part of a string
Sequencing, selection, and iteration
What does an else statement do?

What is binary search?

The loop moves through each item one at a time
What is the difference between a list and an element?
A list is the whole collection; an element is one item inside it
What is the difference between a list and an element?
Because it eliminates half the remaining data each step
How can AND, OR, and NOT be used in loops?
They combine or reverse conditions in loops
Why can a procedure still be useful even if you don't know how it works internally?
Because abstraction allows procedures to be used without understanding the internal code
Why is understanding pseudocode important for the AP exam?
AP pseudocode appears heavily on the multiple choice section
