1.	What is the disadvantage of using splay trees?(a) height of a splay tree can be linear when accessing elements in non decreasing order.(b) splay operations are difficult(c) no significant disadvantage(d) splay tree performs unnecessary splay when a node is only being readThe doubt is from Splay Tree topic in section Binary Trees of Data Structures & Algorithms II got this question during an interview for a job.
Answer» The CORRECT option is (a) height of a SPLAY tree can be LINEAR when accessing elements in non decreasing order. The best I can explain: This will be the case after accessing all n elements in non-decreasing order. SINCE the height of a tree corresponds to the worst-case access time, this means that the actual cost of an operation can be HIGH. However the amortized access cost of this worst case is logarithmic O(log n).
