在 Scala Stack class
,則takeRight()方法用於返回由堆棧的最後n個元素組成的堆棧。
函數定義: def takeRight(n: Int):Stack[A]
返回類型: It returns a stack consisting of the last ‘n’ elements of the stack.
範例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 s1 = Stack(1, 2, 3, 4)
// Print the stack
println(s1)
// Applying takeRight method
val result = s1.takeRight(2)
// Display output
print("Stack containing last two elements: " + result)
}
}
輸出:
Stack(1, 2, 3, 4) Stack containing last two elements: Stack(3, 4)
範例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 s1 = Stack(1, 2, 3, 4)
// Print the stack
println(s1)
// Applying takeRight method
val result = s1.takeRight(3)
// Display output
print("Stack containing last three elements: " + result)
}
}
輸出:
Stack(1, 2, 3, 4) Stack containing last three elements: Stack(2, 3, 4)
