在 Scala Stack class
,则使用dropRight()方法删除堆栈的最后n个元素。
函数定义: def dropRight(n: Int): Stack[A]
返回类型: It returns a new stack that consists of all the elements except the last ‘n’ elements.
范例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 s1 = Stack(6, 2, 3, 4, 5)
// Print the stack
println(s1)
// Applying dropRight method
val result = s1.dropRight(2)
// Displays output
print("Stack after dropRight(2) method: " + result)
}
}
输出:
Stack(6, 2, 3, 4, 5) Stack after dropRight(2) method: Stack(6, 2, 3)
范例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 s1 = Stack(6, 2, 3, 4, 5)
// Print the stack
println(s1)
// Applying dropRight method
val result = s1.dropRight(3)
// Displays output
print("Stack after dropRight(3) method: " + result)
}
}
输出:
Stack(6, 2, 3, 4, 5) Stack after dropRight(3) method: Stack(6, 2)
