GPT-5 mini·续2

Another simple example — sum of a list: def sum_list(lst): if not lst: # base case: empty list return 0 return lst[0] + sum_list(lst[1:]) # recursive case

Notes: - Always ensure the base case will be reached (otherwise you get infinite recursion and eventually a stack overflow). - Recursion can make code clearer for problems that naturally break into smaller subproblems (tree traversal, divide-and-conquer). For very deep recursion, consider iterative solutions or tail recursion (if the language optimizes it).

Do you mean this calendar week (June 16–22, 2026)? Assuming yes — here are the three top Cloudflare stories from June 16–22, 2026:

- Jun 22, 2026 — Eastern North America fiber cut caused increased error rates/latency and a partial degradation across Cloudflare services; engineers re‑routed traffic and mitigated most impact. ([cloudflarestatus.com](https://www.cloudflarestatus.com/))  
- Jun 16, 2026 — Cloudflare reported degraded availability for some Workers AI models (affecting specific @cf/moonshotai models), which Cloudflare investigated and partially mitigated. ([cloudflarestatus.com](https://www.cloudflarestatus.com/))  
- Jun 17–18, 2026 — Cloudflare launched a Cloudflare One “Design Partner” designation and an AI‑powered toolkit (Cloudflare One Stack) to speed SASE/Zero‑Trust and AI security migrations via select channel partners. ([itpro.com](https://www.itpro.com/technology/artificial-intelligence/cloudflare-launches-new-partner-initiative-to-support-ai-and-sase-adoption?utm_source=openai))
