Design a 3-bit counter which counts in the sequence: 001, 011, 010, 110, 111, 101, 100, (repeat) 001, . . . (a) Use D flip-flops. (b) Use T flip-flops. In each case, what will happen if the counter is started in state 000

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
