Scala Queue distinct() 方法与示例
distinct()方法用于从给定队列中删除重复元素。
Method Definition: def distinct: Queue[A]
Return Type: It returns a new queue that contains only distinct elements.
示例 #1:
// Scala program of distinct()
// method
// Import Queue
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating queue
val s1 = Queue(2, 1, 3, 2, 1, 2, 3)
// Print the queue
println(s1)
// Applying distinct() method
val result = s1.distinct
// Display output
print("Queue with distinct elements: " + result)
}
}
输出:
Queue(2, 1, 3, 2, 1, 2, 3)
Queue with distinct elements: Queue(2, 1, 3)
示例 #2:
// Scala program of distinct()
// method
// Import Queue
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating queue
val s1 = Queue("g", "e", "e", "k", "s", "f", "o", "r", "g", "e", "e", "k", "s")
// Print the queue
println(s1)
// Applying distinct() method
val result = s1.distinct
// Display output
print("Queue with distinct elements: " + result)
}
}
输出:
Queue(g, e, e, k, s, f, o, r, g, e, e, k, s)
Queue with distinct elements: Queue(g, e, k, s, f, o, r)
