WebAug 3, 2024 · To link the two lists together we need to link the end of one list to the head of the second. This can be done as follows: node trav=head; while(trav.next!=null){ trav=trav.next; } trav.next=head2; A node ‘trav’ is initiated and pointed at the head of the first list. The first list is traversed until trav reaches the end of the first list. WebOct 7, 2024 · Merging two sorted linked list Algorithm: When the two recursive calls will return the two sorted lists, then we will merge that sorted list into a single list using these below steps.
