Hello everybody, I am puzzled by the execution sequence of the following scala program. Please tell me if it run in the same sequence on your computer,.and it is normal.
Thanks execution sequence according to line number: 26-7-20-27-9-10-12-13-15-7-20-17-18-9-10-12-13-15-7-20-17-18 1. import scala.collection.mutable.ArrayBuffer 2. 3. object TestCase1{ 4. 5. def func(testtttt:Iterator[(Int,Long)]): Iterator[(Int,Long)]={ 6. 7. println("in") 8. val testtttt1=testtttt.flatmap{ 9. case(item,count)=> 10. val newPrefix=item 11. 12. println(count) 13. val a=Iterator.single((newPrefix,count)) 14. 15. func(a) 16. 17. val c = a 18. c 19. } 20. testtttt1 21. } 22. 23. def main(args: Array[String]){ 24. val freqItems = ArrayBuffer((2,3L),(3,2L),(4,1L)) 25. val testtttt = freqItems.toIterator 26. val result = func(testtttt) 27. val reer = result.toArray 28. 29. } 30. }
