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.

fun main(args: Array<String>) {
//sampleStart
val originalMap = mapOf("key1" to 1, "key2" to 2, "key3" to 3)
val filteredMap = originalMap.filterNot { it.value < 3 }
println(filteredMap) // {key3=3}
// original map has not changed
println(originalMap) // {key1=1, key2=2, key3=3}
val matchAllPredicate: ((Map.Entry<String, Int>)) -> Boolean = { it.value > 0 }
val emptyMap = originalMap.filterNot(matchAllPredicate)
println(emptyMap) // {}
//sampleEnd
