Question 3 [Points 7] Modify and run the program shown below in the following way. There is an array of 20 elements defined in the program. The elements of the array are: [20 18 16 14 12 10 8 6 4 2 -10 -20-30 -40 15 23 25 75 45 33]. Thread 1 adds the first four elements (i.e., 20, 18, 16, 14), Thread 2 adds the next four elements (i.e., 12, 10, 8, 6), ..., Thread 5 adds the last four elements (25, 75, 45, 33). Finally, the sum of all the 20 elements is printed by the program include #include # include #define NUMTHREADS 3 int counter-1; void *Prinello(void *threadid) - counter = 2*counter+ (int) threadid; printf("in Thread id: %d Counter: %d ", threadid, counter); pthread_exit(NULL); int main(int argc, char *argvl) pthread t threads[NUM_THREADS] int rc, t; for(t=0,tNUM THREADS,t++){ rinti
