Write a python function genRandomVect that returns a random 1d numpy array of size (50,) where each element is an integer sampled from [0, 100) and no two elements in the vector are the same.
Your code snippet should define the following variable:

Name Type Description
genRando function function that returns a numpy array of shape (50,) that
contains random elements on the interval [0, 100) and
no duplicates

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)?
