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)
