Interesting question on SQL
Consider a database with three relation instances shown below. The primary keys for the Drivers and Cars relation are did and cid respectively and the records are stored in ascending order of these primary keys as given in the tables. No indexing is available in ... If Binary Search is used to locate a tuple in a relation using primary key, then what is the range of n?

Binary Search
Suppose we have the following sorted list: [3, 5, 6, 8, 11, 12, 14, 15, 17, 18] and array data structure is used. We are using recursive binary search algorithm to search an element 8. Which of the following group of number correctly shown the sequence of comparison used to find element 8? (Assume array index starting with 0). a) 11,5,6,8 b) 12,6,11,8

Binary Search
In this given question I find all answers false because while implementing binary seach or tracing it for an example we need to follow same approach Right? if we are taking ceil for evaluation then it should be considered throughout and if we are ... should be traced.Therefore applying both operating individually I find none of the options matching. Correct Me If I am wrong here.
