Inventory Value Calculation

You are given records for various products in a warehouse. Each product record contains its price and the available quantity. Your task is to compute the total inventory value for each product.

The total inventory value is calculated by the formula: $$inventory\_value = price \times quantity$$

A product record is considered valid only if it has exactly two details: a non-negative price (a floating-point number) and a non-negative quantity (an integer). Any record with missing details, additional details, or invalid data types should be ignored.

inputFormat

The first line of input contains an integer T, representing the number of product records. Each of the following T lines contains a product record in the format: name price quantity, where name is a string (without spaces), price is a floating-point number, and quantity is an integer.

outputFormat

Output a JSON object representing the inventory value of each valid product. The keys of the JSON must be the product names and the corresponding values must be the computed inventory value formatted as a floating-point number. The keys should be in lexicographical order.## sample
