Scala BitSet diff() 方法与示例
Scala 位集是一组非负整数,它们表示为打包成 64 位字的可变大小的位数组。 diff() 方法用于计算这个集合和另一个集合的差异。
Method Definition: def +()
Return Type: It returns a set containing diff elements
示例 #1:
// Scala program of diff()
// method
import scala.collection.immutable.BitSet
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating BitSet
val s1 = BitSet(1, 2, 3, 4, 5)
val s2 = BitSet(1, 2, 3)
// Applying diff method
val s3 = s1.diff(s2)
// Displays output
for(elem <- s3)
println(elem)
}
}
输出:
4
5
示例 #2:
// Scala program of diff()
// method
import scala.collection.immutable.BitSet
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating BitSet
val s1 = BitSet(1, 2, 3, 4, 5)
val s2 = BitSet(6, 2, 7, 8)
// Applying diff method
val s3 = s1.diff(s2)
// Displays output
for(elem <- s3)
println(elem)
}
}
输出:
1
3
4
5
