This repository provides a detailed pseudo-code implementation for the user flow of the TodayTix Group (TTG) ticket lottery system. Each folder in this repository represents a distinct component of the feature, containing functionalities such as lottery entry (LotteryFinder), winner selection (WinnerSelector), and ticket claiming (TicketClaimer). The pseudo-code is available in both Java and Swift, illustrating how these processes can be implemented across different platforms (iOS and Android). The code is documented to highlight key programming concepts and integrations with external services like Firebase, PayPal, and Apple/Google Pay APIs. Here is a brief overview of each component:

LotteryFinder: Filters and finds available lotteries based on the user's city and show criteria.

- API: GET /lotteries/{city}
- Objects/Classes: City, Show, Lottery
- Web API: Google Places API for validating city locations if needed.

LotteryEntry: Manages the process of users entering a lottery for a specific show.

- API: POST /lottery/enter
- Objects/Classes: User, Show, LotteryEntry
- Web API: Firebase Authentication for managing user sessions and entries.

WinnerSelector: Algorithm to randomly select winners.

- API: POST /lottery/{lotteryId}/draw-winners

TicketClaimer: Manages the process for winners to claim their tickets within the given time frame.

-API: POST /tickets/claim
- Objects/Classes: Ticket, ClaimTimer, User
- Web API: PayPal API for handling the payment processing

ClaimCloser: A scheduled service that stops accepting ticket claims from winners after the claim time period has ended.

- API: POST /tickets/{ticketId}/close
- Objects/Classes: Ticket, Scheduler
- Web API: Firebase Cloud Function for scheduling tasks

PaymentProcessor: Processes payments and issues tickets upon successful transactions.

- API: POST /tickets/issue
- Objects/Classes: Payment, TicketIssuer, UserOrder
