Scala BitSet -() 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 -() method is utilised to create new set with a given element removed from this set.
Method Definition: def -(elem)
Return Type: It returns new set that contains all elements of this set but that does not contain elem
Example #1:
import scala.collection.immutable.BitSet
object GfG
{
def main(args : Array[String])
{
val bitSet : BitSet = BitSet( 0 , 1 , 2 , 3 )
println(s "Elements in Bitset are = $bitSet" )
val bs 1 : BitSet = bitSet - 0
println(bs 1 )
}
}
|
Output:
Elements in Bitset are = BitSet(0, 1, 2, 3)
BitSet(1, 2, 3)
Example #2:
import scala.collection.immutable.BitSet
object GfG
{
def main(args : Array[String])
{
val bitSet : BitSet = BitSet( 0 , 1 , 2 , 3 )
println(s "Elements in Bitset are = $bitSet" )
val bs 1 : BitSet = bitSet - ( 1 , 3 )
println(bs 1 )
}
}
|
Output:
Elements in Bitset are = BitSet(0, 1, 2, 3)
BitSet(0, 2)
