Read it from start to end, use temp variables to swap direction of pointers. For a linked list of integers that takes in a head pointer and returns a pointer to the head of the reversed list: int* reverseLL(int * head){ if(!head || !head->next) return head; int *prev = NULL; int *next = head; while(next){ head = next; next = next->next; head->next = prev; prev = head; } return head; }
