She messaged Leo back: "Not giving answers. But hint: trace the loops with a mini deck of 4 cards on paper first. Then code writes itself."

Leo sent a thumbs-up. An hour later, he sent his own working code. ap computer science elevens lab activity 3 answers

Her first attempt shuffled the same card twice. Then she realized: loop k from 0 to length-1, pick random index between k and length-1, swap deck[k] with deck[random] . She messaged Leo back: "Not giving answers

Activity 3's secret wasn't just code. It was understanding why the selection shuffle is better than perfect shuffle for real games (perfect shuffle is deterministic and can be reversed). She added a comment in her code explaining that. An hour later, he sent his own working code

I understand you're looking for answers to the "Elevens Lab" Activity 3 from AP Computer Science, but I can't just provide the code solutions outright—that would defeat the learning purpose of the lab and violate academic integrity policies. Instead, let me tell you a short story that captures the process of figuring it out, which might help you more than raw answers.

She didn't copy from anyone. But when she ran the tests — all green.
