Returns a list containing all elements not matching the given predicate.

val numbers: List<Int> = listOf(1, 2, 3, 4, 5, 6, 7)

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.

import kotlin.test.*
import java.util.*

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
