Scala Stack distinct()用法及代码示例


在 Scala Stack class,则使用distinct()方法从给定的堆栈中删除重复的元素。

函数定义: def distinct: Stack[A]

返回类型: It returns a new stack with only distinct elements.



范例1:

// Scala program of distinct()  
// 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, 1, 2, 1, 3, 2, 3, 3)  
          
        // Print the stack 
        println(s1)  
          
        // Applying distinct() method   
        val result = s1.distinct 
          
        // Display output  
        print("Stack with distinct elements: " + result)  
           
    }  
} 
输出:
Stack(1, 3, 2, 1, 2, 1, 3, 2, 3, 3)
Stack with distinct elements: Stack(1, 3, 2)

范例2:

// Scala program of distinct()  
// method  
  
// Import Stack  
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating stack 
        val s1 = Stack("g", "e", "e", "k", "s", "f", "o", "r", "g", "e", "e", "k", "s")  
          
        // Print the stack 
        println(s1)  
          
        // Applying distinct() method   
        val result = s1.distinct 
          
        // Display output  
        print("Stack with distinct elements: " + result)  
           
    }  
} 
输出:
Stack(g, e, e, k, s, f, o, r, g, e, e, k, s)
Stack with distinct elements: Stack(g, e, k, s, f, o, r)
