I have a List<String> like so:
{ "Hello", "ABC", "yo", "This is", "There are", "An App", "Hey", Help" }

I have a query : String = "Hl"

in Kotlin, how would I construct a filter such that the output is:
{ "Hello", Help" }

If I have to implement the algorithm, what would be a good one? Or is the only way to do so is to loop through each char in the query string?

Secondly, if the query is query : String = "a", and let's say the output is
{ "ABC", "There are", "An App"}

I would like to sort this list based on the first index of query, e.g:
{ "ABC", "An App", "There are"}

How should I do so in Kotlin?

My attempt:

val listOfFilteredString = listOfString
                .filter { s-> s.contains(query, ignoreCase = true) }
                .sortedWith(compareBy { s -> s.label.indexOf(query) })

It's not working 😕
