CPU Priority Scheduling-preemptive: Write a Java program to implement a priority scheduling algorithm that uses low number to represent high priority. Your program should first prompts the user to input a list of process ID, arrival time, burst time, and priority for each process to be run on the CPU. The list is terminated by 0 0 0 0 for the process ID, arrival time, burst time, and priority. The program output should draw a Gantt chart that shows the scheduling order of the processes using the Priority scheduling algorithm. Also print the turnaround time, response time, and waiting time for each process along with their average for all processes. Make sure that you have a friendly user interfaces and display very helpful messages.

when you run the lottery ticket schedule, the code does not track the percentage of time a given process actually gets on the CPU. Please modify the code so that this is trackable, try to find the best allocation of tickets to processes to get as close as possible to the expected CPU percentage allocation.
Please show modification in the code
this is C program
#include
#include
#include
#include
// global ticket count
int gtickets = 0;
struct node_t {
int tickets;
struct node_t *next;
};
struct node_t *head = NULL;
void insert(int tickets) {
struct node_t *tmp = malloc(sizeof(struct node_t));
assert(tmp != NULL);
tmp->tickets = tickets;
tmp->next = head;
head = tmp;
gtickets += tickets;
}
void print_list() {
struct node_t *curr = head;
printf("List: ");
while (curr) {
printf("[%d] ", curr->tickets);
curr = curr->next;
}
printf("\n");
}

main(int argc, char *argv[])
{
if (argc != 3) {
fprintf(stderr, "usage: lottery \n");
exit(1);
