Calculate Shipping Cost
Order:
{
"country": "US", // or "CA" for the CA order
"items": [{ "product": "mouse", "quantity": 20},
{"product": "laptop", "quantity": 5}
]
}Note: In your solution, you can pass in an in-memory object that has the same shape as the JSON. You don’t need to worry about parsing JSON for this problem.
The US and CA orders have the same shape; they are just different countries.
Each country/product has a corresponding shipping cost matrix. The cost is stored in the smallest currency unit.
Shipping Cost:
Each product has its own shipping cost
{
"US": [{ "product": "mouse", "cost": 550},
{"product": "laptop", "cost": 1000}
],
"CA": [{ "product": "mouse", "cost": 750},
{"product": "laptop", "cost": 1100}
]
}Write a function called calculate_shipping_cost that takes an order and shipping cost matrix and returns the shipping cost.
Examples:
calculate_shipping_cost(order_us, shipping_cost) == 16000
calculate_shipping_cost(order_ca, shipping_cost) == 20500This problem asks you to compute the total shipping cost for an order using a country-specific shipping matrix. The key idea is to look up the correct country first, then map each product to its shipping cost and sum quantity × unit cost across all items. Because prices are given in the smallest currency unit, the solution can use plain integer arithmetic without any decimal handling.
