IN-TREEISH-TABLE(T, k) p= T[HASH(T, k)] while p * NIL ifkp.key p=p.right else 1a. return TRUE return FALSE IN-TREEISH-TABLE takes a hash table T and a key k as its parameters. The table T resolves collisions by chaining, but instead of using linked lists in its buckets, it uses binary search trees. In the trees, each node p has three slots. The slot p.key is a key. The slots p.left and p.left point to p's left and right subtrees, respectively. IN-TREEISH-TABLE first uses a hash function HASH to find a tree in the table, then searches that tree for k. If it finds k, then it returns TRUE, otherwise it returns FALSE. In the best case, how many key comparisons will IN-TREEISH-TABLE perform? Briefly explain your answer. 1b In the average case, how many key comparisons will IN-TREEISH-TABLE perform? Briefly explain your answer. Hint: assume simple uniform hashing is in effect. 1c. In the worst case, how many key comparisons will IN-TREEISH-TABLE perform? Briefly explain your answer. Hint: assume simple uniform hashing fails. #2
