... FIND still runs in O(log n) time in the worst case; path compression increases the cost by only most a constant factor. But we have good reason to suspect that this upper bound is no longer tight. Our new algorithm memoizes the results of each FIND, so if we are asked to FIND the same item twice in ...

... requires shifting all elements down one space in the array to make room, whereas deleting the first element requires shifting all elements in the array up one. In the worst case insertion and deletion is an order(N) operation and on average order(N/2) so linear time is still required. Building a ...

... One way to reduce the cost of paging STs in and out of memory is to transmit only the leaves of the ST. The internal nodes can be generated in memory without additional I/O. A more effective approach is to partition an ST into multiple, smaller subtrees, each representing a certain part of the data. ...
