Write a Python function to find all prime numbers up to n using the Sieve of Eratosthenes.

Here's an efficient implementation:
# Sieve of Eratosthenes — O(n log log n) def sieve(n: int) -> list: is_prime = [True] * (n + 1) is_prime[0] = is_prime[1] = False for i in range(2, int(n**0.5) + 1): if is_prime[i]: is_prime[i*i::i] = [False] * len(is_prime[i*i::i]) return [i for i, p in enumerate(is_prime) if p]

FAQ

Questions, answered

How does pay-as-you-go work? +

You top up your wallet with as little as $1. Every AI request is metered — we count the tokens in and out, apply the model's per-token price, and deduct the exact cost from your balance. No monthly fees, no expiry, no surprises.

Do I need to pay anything upfront? +

No. You get 10 free messages a day on free-tier models (Groq, Gemini Flash) — those cost you nothing and cost us nothing. When you want premium models like GPT-4o or Claude, you top up first, so you're always in control of spend.

Which AI engines are available? +

OpenAI (GPT-4o, GPT-4o mini), Anthropic (Claude 3.5/3.7), Google (Gemini 2.0/2.5), Groq (Llama 3.3, Mixtral, Gemma), OpenRouter (DeepSeek, Qwen, 200+ models) and Mistral. More engines are added as they launch.

How is the WhatsApp agent different from a chatbot? +

Our agent is a state machine: it classifies intent, fills slots (service, date, time, name), and then performs real actions against your data — checking actual appointment availability and real stock levels. It never guesses a slot or a price, and it hands off to your team for anything medical.

Can I use the wallet service in my own apps? +

Yes — the shared wallet service is an internal API with HMAC-signed service-to-service auth. AppleVine, E-2GO, HealthForce and Cubed Capfin can all create accounts, credit/debit balances, transfer funds and request payouts. Contact us for API keys.

What payment methods do you support? +

EcoCash, CBZ iVeri, Paystack, Flutterwave, M-Pesa, Stripe and PayPal — with plans and top-ups priced in USD, ZWG, ZAR, KES, NGN, GHS and more.
