In Scala Stack class
, the dropRight() method is utilized to drop the last ‘n’ elements of the stack.
Method Definition: def dropRight(n: Int): Stack[A]
Return Type: It returns a new stack that consists of all the elements except the last ‘n’ elements.
Example #1:
// 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)
