Essential knowledge for this set

These are the essential knowledge (EKS) statements from the AP Computer Science A Course and Exam Description that the 56 questions in this set assess, grouped by topic and learning objective. The table under each question links here.

Topic 2.11: Nested Iteration

2.11.A — Develop code to represent nested iterative processes and determine the result of these processes.

• 2.11.A.1 Nested iteration statements are iteration statements that appear in the body of another iteration statement. When a loop is nested inside another loop, the inner loop must complete all its iterations before the outer loop can continue to its next iteration.

Topic 2.12: Informal Run-Time Analysis

2.12.A — Calculate statement execution counts and informal run-time comparison of iterative statements.

• 2.12.A.1 A statement execution count indicates the number of times a statement is executed by the program. Statement execution counts are often calculated informally through tracing and analysis of the iterative statements.
