# This program simualtes the backend of a ticket purchasing system

# Price per visitor is $5
# Price per member is $3.50

# You are to do the following
# 1. Identify all banned visitors with a filter call
# 2. Determine the memberships status of all applicants
# 3. Calculate the total price for all eligible visitors
# 4. For each valid visitor, return a corresponding ticket in Dictionary form
# 5. Return an error via thrown exception if applicants is empty
# Complete everything above in a function called processRequest
# Your should abstract out function as much as reasonably possible
