The Buffered Repository Tree (BRT). Stores key-value pairs (k,v) Supported operations: I NSERT (k,v) inserts a new pair (k,v) into T E XTRACT (k) extracts all pairs with key k. Web(say by DFS). The running time is . A more elegant algorithm always starts at simple ob-servations. Suppose we run DFS on , we get a DFS tree. If the root has two or more children, it is an ar-ticulation point. Moreover, a leaf is not an articulation point. Some parts of the tree have edges that ’climbs’ to the
