Is "ABCBDCCDCDDDDDD" a feasible output? If no, why? 6. How many processes are created (including the top level process) with the above code? What is the largest value of i among all the processes before they exit?
```c++ #include <unistd.h> #include <stdio.h> int main() { write(1, "j", 1); int c1 = fork(); write(1, "m", 1); int c2 = fork(); write(1, "u", 1); if (c1 == 0 || c2 == 0) { write(1, "!", 1); } return 0; } ```
