AP CSP: Big Idea 3 Quiz

Type your name exactly as it should appear on your certificate, then press Start.

Your name locks once you start. Come back to this quiz across several days if you want: your progress is saved automatically on this device. Every wrong answer costs more than a right one earns, so random guessing will lose points on average. There is no way to start over from this page, so slow down and read each question.

a ← expression	Stores the value of the expression in a. Only the most recent assignment sticks.
DISPLAY(x)	Shows x, followed by a space.
a MOD b	The remainder after dividing a by b.
= ≠ < > ≤ ≥	Relational operators. Each gives true or false.
AND, OR, NOT	AND is true when both sides are true. OR is true when at least one side is true. NOT flips true and false.
IF (condition) {...} ELSE {...}	Runs the first block when the condition is true, otherwise the ELSE block. Never both.
REPEAT n TIMES {...}	Runs the block exactly n times.
REPEAT UNTIL (condition) {...}	Checks the condition before each pass and stops as soon as it is true.
FOR EACH item IN list {...}	Runs the block once for every item in the list, in order.
list[i], LENGTH(list)	The item at index i, and the number of items. The first item is at index 1.
APPEND, INSERT, REMOVE	APPEND(list, v) adds to the end. INSERT(list, i, v) adds at index i and shifts later items over. REMOVE(list, i) removes the item at index i.
