1️⃣What is rememberin Jetpack Compose?
Answer:
In Jetpack Compose, remember is used to keep a value in memory during recomposition. It ensures that the stored value is not lost when the UI updates.
Example:

@Composable
fun Counter() {
    var count by remember { mutableStateOf(0) } //Here, count stays the same even if the UI recomposes.

    Button(onClick = { count++ }) {
        Text("Count: $count")
    }
}

Key Points:
- Keeps values in memory during recomposition.
- Used mutableStateOfto manage state.
- Prevents unnecessary recalculations.
