# exercise3_product_search.py
# 🐛 BUG HUNT + EXTEND — This file has 2 bugs AND is missing a feature.
#
# SCENARIO: OutdoorGear product search with filtering.
#
# TASK A (Fix): Find and fix the 2 bugs using Copilot /fix
# TASK B (Extend): Ask Copilot to add a sort_by_price() function
#   Prompt to use: "Add a sort_by_price(products, ascending=True) function
#                   that sorts the search results by price"
#
# EXPECTED OUTPUT after fixing:
#   search("boot")   → [{"name": "TrailBlazer X200", "price": 189.99, "category": "footwear"}]
#   search("tent")   → [{"name": "Summit Pro Tent",  "price": 349.00, "category": "camping"}]
#   search("xyz")    → []
#   search("")       → all 5 products
#
# HOW TO USE:
#   Step 1 — Fix bugs:  Select all → Copilot Chat → /fix
#   Step 2 — Extend:    Ctrl+I (inline chat) → type the prompt above
#   Step 3 — Test:      Run the tests at the bottom
