Cоnsider the fоllоwing multi-threаded C pseudocode: 1. void insertQueueA(void* dаtа) { 2. lock(&mutexA); 3. pushQueue(&queueA, data); 4. cond_signal(&cv); 5. unlock(&mutexA); 6. } 7. void insertQueueB(void* data) { 8. lock(&mutexB); 9. pushQueue(&queueB, data); 10. cond_signal(&cv); 11. unlock(&mutexB); 12. } 13. void* getDataFromQueueAOrQueueB() { 14. void* data = NULL; 15. lock(&mutexC); 16. while (1) { 17. lock(&mutexA); 18. if (!isEmpty(&queueA)) { 19. data = popQueue(&queueA); 20. unlock(&mutexA); 21. break; 22. } 23. unlock(&mutexA); 24. lock(&mutexB); 25. if (!isEmpty(&queueB)) { 26. data = popQueue(&queueB); 27. unlock(&mutexB); 28. break; 29. } 30. unlock(&mutexB); 31. cond_wait(&cv, &mutexC); 32. } 33. unlock(&mutexC); 34. return data; 35. } Select the best steps for exposing the race condition in this code. Assume line ranges are inclusive. Step 1: [step1] Step 2: [step2] Step 3: [step3]
