- Expect clear handling of overlapping regions.
- Look for edge cases where rectangles touch but do not overlap.
- Expect questions about uniform distribution and radius scaling for correctness.
解题流程
- 1. 明确窗口/状态定义
- 2. 更新状态并维护约束
- 3. 用边界样例验证
常见失分点
- Forgetting to subtract the overlapping area, leading to inflated totals.
- Generating the radius uniformly without square root leads to biased point distribution towards the center.
- Failing to check that all four sides are positive and equal length.
