Now imagine two cards needed to support each other simultaneously, it would be physically impossible to build. This is exactly the problem we face with dependencies in software development. 🔁 A Real-World Example In this scenario: AuthenticationService needs UserService to verify user permissions UserService needs ProfileService to get user details ProfileService needs AuthenticationService to access secure data This creates an impossible situation: none of these services can be initialized because each depends on another that isn’t yet created.
