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)
