// Scala program of dropRight() // method // Import Stack import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating stack val s 1 = Stack( 6 , 2 , 3 , 4 , 5 ) // Print the stack println(s 1 ) // Applying dropRight method val result = s 1 .dropRight( 2 ) // Displays output print( "Stack after dropRight(2) method: " + result) } } |
Output:
Stack(6, 2, 3, 4, 5) Stack after dropRight(2) method: Stack(6, 2, 3)
Example #2:
// Scala program of dropRight() // method // Import Stack import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating stack val s 1 = Stack( 6 , 2 , 3 , 4 , 5 ) // Print the stack println(s 1 ) // Applying dropRight method val result = s 1 .dropRight( 3 ) // Displays output print( "Stack after dropRight(3) method: " + result) } } |
Output:
Stack(6, 2, 3, 4, 5) Stack after dropRight(3) method: Stack(6, 2)
