inline fun CharArray.filterNot( predicate: (Char) -> Boolean ): List<Char>
inline fun <T> Iterable<T>.filterNot( predicate: (T) -> Boolean ): List<T>
Returns a list containing all elements not matching the given predicate.
inline fun <K, V> Map<out K, V>.filterNot( predicate: (Entry<K, V>) -> Boolean ): Map<K, V>
Returns a new map containing all key-value pairs not matching the given predicate.
The returned map preserves the entry iteration order of the original map.
