The entire sourse code

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <pthread.h>

#define THREADS 10 // Number of Thread

//bridge declared with array of character and integer value

// Global Variable
int North = 1; //For North Number

char array[5] = "North"; // North
printf("%s Tunbridge #%d farmer can cross the bridge\n", array, North);
Bridge(array, North);
printf("%s Tunbridge #%d farmer has left the bridge\n\n", array, North);

}

//main method
int main(){
pthread_t North[THREADS]; // North Thread
pthread_t South[THREADS]; // South Thread
pthread_mutex_init(&mutex1,NULL);

for(int i = 0; i < THREADS; i++){
int CreateFirst = pthread_create(&North[i], NULL, NorthFarmer, NULL);
int CreateSecond = pthread_create(&South[i], NULL, SouthFarmer, NULL);
if(CreateFirst != 0 || CreateSecond != 0){
fprintf(stderr, "Thread Create Failed");
return 1;
}
}

for(int i = 0; i < THREADS; i++){
int JoinFirst = pthread_join(North[i],NULL);
int JoinSecond = pthread_join(South[i],NULL);

Use C language , pointer limit use //#include <stdio.h> //#include <stdlib.h> //#include <time.h> For example, I have random array [4,2,7,1,9,8,0]. Sort the array's index but cannot change the position of item in the array, if you copy the array to a new array, you also cannot change the item's position in array. The index now is[0,1,2,3,4,5,6] The output should be[6,3,1,0,2,5,4]
