Raise on Invalid Discount

Easy ⏱ 8 min 82% acceptance ★★★★★ 4.6

Write apply_discount(price, pct) that returns the discounted price — but raises ValueError with the message 'pct must be between 0 and 100' when pct is outside that range. Validating inputs by raising (not returning error codes) is the Pythonic contract.
