Buat fungsi recommendStrategy(requirements) yang menerima object requirements dan merekomendasikan deployment strategy.

Input: { zeroDowntime, instantRollback, gradualRollout, simplicity }

Rules (prioritas berurutan):

1. Jika gradualRollout true → "canary"
2. Jika instantRollback true → "blue-green"
3. Jika zeroDowntime true → "rolling"
4. Jika simplicity true → "recreate"
5. Default → "rolling"

Hint

• Deployment strategy menentukan bagaimana versi baru di-release.
• Rolling: bertahap. Blue-green: switch. Canary: gradual rollout.
• Zero downtime + rollback → "blue-green". Gradual → "canary".
