Scala BitSet dropWhile() method with example
Scala Bitsets are sets of non-negative integers which are represented as variable-size arrays of bits packed into 64-bit words. The drop() method is utilised to drop longest prefix of elements that satisfy a predicate.
Method Definition: def drop()
Return Type: It returns the longest suffix of collection whose first element does not satisfy p.
Example #1:
// Scala program of dropWhile() // method import scala.collection.immutable.BitSet // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a list var s 1 = BitSet( 1 , 3 , 5 , 4 , 2 ) // Print the BitSet println(s 1 ) // Applying dropWhile method var res = s 1 .dropWhile(x => {x % 2 ! = 0 }) // Displays output println(res) } } |
Output:
BitSet(1, 2, 3, 4, 5) BitSet(2, 3, 4, 5)
Example #2:
// Scala program of dropWhile() // method import scala.collection.immutable.BitSet // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a list var s 1 = BitSet( 15 , 17 , 21 ) // Print the BitSet println(s 1 ) // Applying dropWhile method var res = s 1 .dropWhile(x => {x % 3 == 0 }) // Displays output println(res) } } |
Output:
BitSet(15, 17, 21) BitSet(17, 21)
