下⾯的代码⽚段⽤于反转单链表 ，请进⾏（ ） 修改 ，使其能正确实现相应功能。
1 ListNode* reverseLinked List(ListNode* head) {
2 ListNode* prev = nullptr;
3 ListNode* current = head;
4 while (current != nullptr) {
5 ListNode* next = current->next;
6 current->next = next;
7 prev = current;
8 current = next;
9 }
10 return prev;
11 }
current->next = next; 应该改为 current->next = prev;
ListNode* next = current->next; 应该改为 ListNode* next = prev->next;
current != nullptr 应该改为 current->next != nullptr
ListNode* prev = nullptr; 应该改为 ListNode* prev = head;
