inline fun CharSequence.any(predicate: (Char) -> Boolean): Boolean

Returns true if at least one character matches the given predicate.

Samples

import samples.*

fun main() { 
   //sampleStart 
   val isEven: (Int) -> Boolean = { it % 2 == 0 }
val zeroToTen = 0..10
assertTrue(zeroToTen.any { isEven(it) })
assertTrue(zeroToTen.any(isEven))

val odds = zeroToTen.map { it * 2 + 1 }
assertFalse(odds.any { isEven(it) })

val emptyList = emptyList<Int>()
assertFalse(emptyList.any { true }) 
   //sampleEnd
