In Scala Stack class
, the drop() method is utilized to drop the first ‘n’ elements from the top of the stack.
Method Definition: def drop(n: Int): Stack[A]
Return Type: It returns a new stack with all the elements except the first ‘n’ ones from the top of the given stack.
Example #1:
// Scala program of drop() // 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 drop method
val result = s 1 .drop( 2 )
// Displays output
print( "Stack after drop(2) method: " + result)
}
} |
Output:
Stack(6, 2, 3, 4, 5) Stack after drop(2) method: Stack(3, 4, 5)
Example #2:
// Scala program of drop() // 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 drop method
val result = s 1 .drop( 3 )
// Displays output
print( "Stack after drop(3) method: " + result)
}
} |
Output:
Stack(6, 2, 3, 4, 5) Stack after drop(3) method: Stack(4, 5)
