在 Scala Stack class
,則使用tail()方法返回一個新堆棧,該堆棧由除第一個元素外的所有元素組成。
函數定義: def tail: Stack[A]
返回類型: It returns a new stack that consists of all the elements except the first one.
範例1:
// Scala program of tail()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stack
val s1 = Stack(1, 3, 2, 7, 6, 5)
// Print the stack
println(s1)
// Applying tail method
val result = s1.tail
// Display output
print("Elements of the queue except the first one: " + result)
}
}
輸出:
Stack(1, 3, 2, 7, 6, 5) Elements of the queue except the first one: Stack(3, 2, 7, 6, 5)
範例2:
// Scala program of tail()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stack
val s1 = Stack(5, 3, 2, 7, 6, 1)
// Print the stack
println(s1)
// Applying tail method
val result = s1.tail
// Display output
print("Elements of the queue except the first one: " + result)
}
}
輸出:
Stack(5, 3, 2, 7, 6, 1) Elements of the queue except the first one: Stack(3, 2, 7, 6, 1)
