Write a function to reverse a linked list | GeeksforGeeks

Iterative Method Iterate trough the linked list. In loop, change next to prev, prev to current and current to next. Implementation of Iterative Method #include #include /* Link list node */ struct node { int data; struct node* next; }; /* Function to reverse the linked list */ static void reverse(struct node** head_ref) { struct node* prev = NULL; struct node* current = *head_ref; struct node* next; while (current != NULL) { next = current->next; current->next = prev; prev = current; current = next; } *head_ref = prev;
