Hi there!

This PR contributes a set of new Android interview questions as part of the Hacktoberfest initiative.

I added a crucial new interview question to the list, focusing on side-effect handlers in Jetpack Compose (LaunchedEffect, SideEffect, and DisposableEffect).

Changes Made

Added a new question: "Compare and contrast LaunchedEffect, SideEffect, and DisposableEffect. Provide a clear use case for each one."
Included a clear, structured answer highlighting the key differences in terms of lifecycle, use cases, and cleanup requirements.

Closes #28

This question is important as it tests a candidate's understanding of how to manage asynchronous logic and lifecycle interactions within the declarative paradigm of Compose. This is a fundamental concept and a common point of confusion for many developers.

Summary by CodeRabbit

  • Documentation
    • Expanded Jetpack Compose guidance with clear comparisons of LaunchedEffect, SideEffect, and DisposableEffect, outlining when each runs, relation to composition, side-effect timing, and practical use cases.
    • Clarifies decision-making for choosing the appropriate effect in different scenarios.
    • No runtime or functional changes; documentation-only update.

Poem

I hop through lines of README light,
Nibbling notes on effects tonight.
Launched, Side, Disposable—clear and bright,
I tidy words till usage feels right. 🥕

435-442: Great clarification on DisposableEffect.

The revised explanation now correctly emphasizes its synchronous execution path and onDispose cleanup, clearly distinguishing it from LaunchedEffect. Nicely done.

This commit corrects the description to clarify that:
- The effect block runs synchronously, not as a coroutine.
- Its primary purpose is for non-suspending side effects that require explicit teardown logic (e.g., registering listeners).
- It is distinct from LaunchedEffect, which is specifically for launching coroutines.
