Difficulty: Hard |
Topic: Iteration (nested loop count) |
Cycle: 2 (Advanced)
Why This Answer?
Outer loop runs 2 times, inner loop runs 3 times each → 2 × 3 = 6.
Common Mistake
Watch Out!
Adding instead of multiplying the loop counts.
AP Exam Strategy
Nested loops multiply: outer iterations × inner iterations.
