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 select all elements except n items.
Method Definition: def drop()
Return Type: It returns a iterable collection except the n items
Example #1:
// Scala program of drop() // method import scala.collection.immutable.BitSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating BitSet
val s 1 = BitSet( 1 , 2 , 3 , 4 , 5 )
// Applying dropRight method
val s 2 = s 1 .dropRight( 2 )
// Displays output
for (elem < - s 2 )
println(elem)
}
} |
Output:
1 2 3
Example #2:
// Scala program of drop() // method import scala.collection.immutable.BitSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating BitSet
val s 1 = BitSet( 1 , 2 , 3 , 7 , 9 , 4 , 5 )
// Applying dropRight method
val s 2 = s 1 .dropRight( 3 )
// Displays output
for (elem < - s 2 )
println(elem)
}
} |
Output:
1 2 3 4
