Describe the undesireable race condition in the attached code:

void *fl (void* args) {
int id = argx -> id
int mysum = args -> sum
int* arr = args -> array
for (i=start; i<end; i++) {
sum += arr[i]
}
int main() {
int sum
int* arr
pthread_create(&thread0, NULL, fl, &args[0])
pthread_create(&thread1,
NULL, fl, &args[1])
Transcribed Image Text:void *fl (void* args) { int id = argx -> id int mysum = args -> sum int* arr = args -> array for (i=start; i<end; i++) { sum += arr[i] } int main() { int sum int* arr pthread_create(&thread0, NULL, fl, &args[0]) pthread_create(&thread1, NULL, fl, &args[1])
