g Practice using test cases to debug a function. This is the same function we developed earlier in the iterative development lesson. It is a function that takes as arguments a string and a list of strings, and returns the a list of indices where the first string was found in the list. It is to be case insensitive and handle partial words as well. Check back in 5.2 for a more complete definition. Find the error in this version of that code and fix it.

Research data that is presented using descriptive language is said to be

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)?
