data structurestreespath traversalWe present two results for path traversal in trees, where the traversal is performed in an asymptotically optimal number of I/Os and the tree structure is represented succinctly. Our first result is for bottom-up traversal that starts with a node in a tree on ...

But a hierarchical data structure like a tree can be traversed in different ways. Tree traversal Let's think about how we can read the elements of the tree in the image shown above. Starting from top, Left to right 1 -> 12 -> 5 -> 6 -> 9 Starting from bottom, Left to right ...
