Question: Let A be an array of n sorted integers, and let B be an (almost) identical copy of A. The only difference between B and

Let A be an array of n sorted integers, and let B be an (almost) identical copy of A. The only difference between B and A is that B is missing exactly one number that A contains.

(a) Describe an algorithm running in O(log n) time for determining the missing number for any given array A and B.

(b) Analyze the running time of your algorithm to justify that it runs in O(log n) time.
