Scala 设置 splitAt() 方法与示例

splitAt()方法用于将给定的集合拆分为指定位置的前缀/后缀对。

Method Definition: def splitAt(n: Int): (Set[A], Set[A])
Where, n is the position at which we need to split.

Return Type: It returns a pair of sets consisting of the first n elements of this set, and the other elements.

示例 #1：

// Scala program of splitAt() 
// method 
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a set 
        val s1 = Set(4, 12, 2, 31) 
          
        // Applying splitAt method 
        val result = s1.splitAt(2)
          
        // Display output
        println(result)
    } 
} 

输出：

(Set(4, 12), Set(2, 31))

示例 #2：

// Scala program of splitAt() 
// method 
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a set 
        val s1 = Set(1, 2, 3, 4) 
          
        // Applying splitAt method 
        val result = s1.splitAt(2)
          
        // Display output
        println(result)
    } 
} 

输出：

(Set(1, 2),Set(3, 4))
