Output:
4
Example 2:
Scala
// Scala program of count() // method import scala.collection.immutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating listset val m 1 = ListSet( 1 , 2 , 3 , 4 , 5 , 7 ) // Applying filter method val result = m 1 .count( _ < 1 ) // Displays output println(result) } } |
