Draw the process hierarchy tree for this program:

#include #include #include int count = 0; main() pid_t x;

x = fork(); count = count + 5; printf(A: count is %d ,count); /* Line L */ if (x == 0) { count = count + 10; fork(); printf(B: count is %d ,count); /* Line M */ } else { count = count + 15; printf(C: count is %d ,count); /* Line N */ } }
