Modify the following code to do the following: - Task 1 (50 pts). Eliminate the deadlock by avoiding circular waiting. (Hint: change the order to access chopsticks for some philosophers.) - Task 2 (50 pts). Eliminate the deadlock by avoiding hold and wait. In other words, if a philosopher is not able to obtain the right chopstick, he/she will release the left chopstick immediately. (Hint: Use Pthread Mutex to solve the problem.) -Task 3 (50 pts extra credit). Eliminate the deadlock by limiting that at most 3 philosophers are able to compete for the chopsticks at the same time. (Hint: Use Pthread Conditional Variable to solve the problem.)#include #include #include #include #include #define NUMP 5pthread_mutex_t fork_mutex[NUMP];int main(int argc, char* argv[]){ int i; pthread_t diner_thread[NUMP]; int dn[NUMP]; void *diner(); for (i=0;i
