Why did my whole list vanish?
Short answer. You moved start before linking the new node, so the rest of the list was lost.
How do you delete the first node?
start = start.next.
Remember
| Link the new node first |
| Then move start |
| Delete: skip the node |
One wrong order, and the whole list is lost! To insert, link n to start first. Then move start to n. To delete, move start to the next node. Remember. Link the new node first. Then move start. To delete, skip the node.
