Scala SortedSet dropWhile() method with example
The dropWhile() method is utilized to drop the longest prefix of elements from the SortedSet that satisfies the stated condition.
Method Definition: def dropWhile(p: (A) => Boolean): SortedSet[A]
Return Type: It returns a TreeSet containing all the elements after dropping the longest prefix of elements from the SortedSet that satisfies the stated condition.
Example #1:
// Scala program of dropWhile() // method import scala.collection.immutable.SortedSet // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a list var s1 = SortedSet(1, 3, 5, 4, 2) // Print the SortedSet println(s1) // Applying dropWhile method var res = s1.dropWhile(x => {x % 2 != 0}) // Displays output println(res) } } |
Output:
TreeSet(1, 2, 3, 4, 5) TreeSet(2, 3, 4, 5)
Example #2:
// Scala program of dropWhile() // method import scala.collection.immutable.SortedSet // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a list var s1 = SortedSet(15, 17, 21) // Print the SortedSet println(s1) // Applying dropWhile method var res = s1.dropWhile(x => {x % 3 == 0}) // Displays output println(res) } } |
Output:
TreeSet(15, 17, 21) TreeSet(17, 21)
