在 Scala Stack class
,則使用reverse()方法以相反的順序返回堆棧。
函數定義: def reverse: Stack[A]
返回類型: It returns a stack with the reverse order.
範例1:
// Scala program of reverse()
// 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, 5, 6)
// Print the stack
println(s1)
// Applying reverse method
val result = s1.reverse
// Display output
print("Reversed stack: " + result)
}
}
輸出:
Stack(1, 2, 3, 4, 5, 6) Reversed stack: Stack(6, 5, 4, 3, 2, 1)
範例2:
// Scala program of reverse()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stack
val s1 = Stack(5, 2, 13, 7, 1, 3)
// Print the stack
println(s1)
// Applying reverse method
val result = s1.reverse
// Display output
print("Reversed stack: " + result)
}
}
輸出:
Stack(5, 2, 13, 7, 1, 3) Reversed stack: Stack(3, 1, 7, 13, 2, 5)
