I was reading couple of articles on heavy light decomposition of trees. There I kept getting this chaining terms which I find very difficult to understand.
Could someone please explain how any tree not necessarily a binary tree and does not necessarily have a root and unordered CAN be viewed as just a chain of nodes ? (In simple language) A small example or code snippet would be highly appreciated.
Thanks.
