AP Computer Science Principles

An original challenge form spanning all five big ideas: multistep algorithm tracing, data and privacy reasoning, evidence-based innovation analysis, and a Create-style written-response rehearsal.

Written Response 1: Program purpose and design

Written Response 2: Algorithms, testing, and abstraction

This supplied example is a practice surrogate for written-response rehearsal. On the actual assessment, students answer using their own submitted Create project and Personalized Project Reference. The example receives a nonempty list of positive integer session lengths and a positive integer time budget. It returns the 1-based positions of every session that fits the budget; an empty result means none fit.
