带有示例的 Scala Stack takeRight() 方法

在 Scala Stack class中， takeRight()方法用于返回由堆栈的最后 'n' 个元素组成的堆栈。

Method Definition: def takeRight(n: Int):Stack[A]

Return Type: It returns a stack consisting of the last ‘n’ elements of the stack.

示例 #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) 
         
    } 
} 

输出：

Stack(1, 2, 3, 4)
Stack containing last two elements: Stack(3, 4)

示例 #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) 
         
    } 
} 

输出：

Stack(1, 2, 3, 4)
Stack containing last three elements: Stack(2, 3, 4)
