Given the following pseudo code, assume that there is no other application running in the system. The system has only one CPU and the code starts execution on time 10:00 AM. We also assume that each statements execution time can be ignored. Assume that the Sleep function used in the code is a blocking system call. What is the print out if the code is executed on an OS with many-to-one multithreading model? What if the OS using one-to-one multithreading model? Explain your answer.

int x=0;

func(){

x+=20;

Sleep(1 hour);

Print current time;

}

void main(){

CreateThread(func);

Sleep(1 hour);

Print current time;

}
