You insert 5 into the min-heap [7, 12, 9, 20]. Where does it end up?
Options

The real thing, not a picture of it. Try it.

01

Before the answer, not just after

Lessons ask first. Trying to answer, even wrongly, makes the explanation that follows stick.

02

Wrong answers explained

Each wrong option says what it gets wrong, and names the misconception behind it.

03

Mistakes come back

An idea you slipped on returns later in the course and in your review, until it holds.
