How to reverse a linked list in c
WebSo, after all the recursive calls ‘q’ will be pointing to the last node and ‘p’ will be pointing to null. While returning time ‘q’ will point to node ‘4’ and ‘p’ will point to node ‘3’. Here we will modify ‘p’ as ‘p->next = q’. In this way, we will reverse all … Web2 dagen geleden · In this tutorial, we have implemented two approaches in JavaScript programming language for reversing a given linked list in alternative group of k …
