How do suspending functions work in Kotlin?

Coroutines in Kotlin allow you to write asynchronous code in a sequential style, making it more readable and maintainable compared to traditional callbacks or Futures.

Key points:

1. Suspending functions: Functions marked with suspend can suspend their execution without blocking the thread. When the asynchronous operation completes, the coroutine resumes from where it was suspended.

2. Compiler transformation: Kotlin compiler transforms suspending functions. Instead of returning a value directly, suspending functions receive an additional parameter - Continuation.

3. Continuation: An object that encapsulates the
