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