Consider a sequence of m operations on a splay tree, each a search, insertion, or deletion, starting from a splay tree with zero keys. also, let f(i) denote the number of times item i is accessed, and let n be the total number of insertions. assuming each item is accessed at least once, the total running time for performing the sequence of operations is
