What is BitSet in Scala

Question

Can any help me out with the above question and how does BitSet works?

Answer 1

Hey,

A BitSet is a set of non-negative integers depicted as arrays. These arrays are variable in size and packed into 64-bit words. The largest number in a BitSet determines its memory footprint. 

Let’s take an example:

scala> import scala.collection.immutable._

import scala.collection.immutable._

scala> var nums=BitSet(7,2,4,3,1)

nums: scala.collection.immutable.BitSet = BitSet(1, 2, 3, 4, 7)

scala> nums+=9 

scala> nums
