Warehouse Package Management

This problem simulates a warehouse package management system. The warehouse stores packages in various compartments where each compartment is identified by a unique code. Each package has an integer weight and a fragility indicator. You are required to process a series of operations to add packages to the warehouse and to query the sum of weights within a specified lexicographical range of compartment codes.

The operations are defined as follows:

• ADD code weight fragile: Adds a package with the given compartment code, weight, and fragility status. The fragile field is Y if the package is fragile and N otherwise.
• QUERY condition start_code end_code: Computes and outputs the sum of the weights of packages whose compartment codes fall in the interval \( [start\_code,\; end\_code] \) (inclusive). The condition can be one of the following:
  • ALL: Consider all packages.
  • FRAGILE: Consider only fragile packages (i.e. packages with fragile status Y).
  • NONFRAGILE: Consider only non-fragile packages (i.e. packages with fragile status N).

Note that string comparisons are case-sensitive. For instance, compartment codes "A1" and "a1" are considered different.

Example:

Input:
5
ADD A1 100 Y
ADD B2 200 N
ADD C3 150 Y
QUERY ALL A1 C3
QUERY FRAGILE A1 C3
Output:
450
250

inputFormat

The first line of the input contains an integer T representing the number of operations. Each of the following T lines contains an operation in one of the following formats:

1. ADD code weight fragile

   • code: A unique compartment code (string). • weight: The weight of the package (an integer). • fragile: A string that is either "Y" (fragile) or "N" (non-fragile).

2. QUERY condition start_code end_code

   • condition: One of "ALL", "FRAGILE", or "NONFRAGILE". • start_code, end_code: Strings representing the lexicographical range of compartment codes (inclusive).

All operations must be processed in the order they are provided.

outputFormat

For each QUERY operation, output an integer on a new line representing the sum of the weights of the packages that satisfy the query condition and whose compartment codes fall within the given lexicographical range.## sample
