fun <T> Sequence<T>.dropWhile( predicate: (T) -> Boolean ): Sequence<T>
Returns a sequence containing all elements except first elements that satisfy the given predicate.
The operation is intermediate and stateless.
import kotlin.test.*
fun main(args: Array<String>) {
//sampleStart
val chars = ('a'..'z').toList()
println(chars.drop(23)) // [x, y, z]
println(chars.dropLast(23)) // [a, b, c]
println(chars.dropWhile { it < 'x' }) // [x, y, z]
println(chars.dropLastWhile { it > 'c' }) // [a, b, c]
//sampleEnd
