Creating your own findViewById equivalent for View
livecode
Task condition
It is necessary to implement a function that searches for a nested View by its identifier, mimicking the behavior of the standard findViewById method. When writing the solution, you can use the following properties and functions provided in the SDK:
View.id: IntViewGroup.childCount: Intfun ViewGroup.getChildAt(index: Int): Viewfun ViewGroup.children(): Sequence<View>
You need to write a universal function that returns the found element of the required type or null if the element with the specified id is not found.
fun <T: View> findViewById(root: View, id: Int): T?
