Investigate the situation, context, or task.
Evaluate solution options.
Learning Objective:
For binary search algorithms:
a. Determine the number of iterations
b. Explain the requirements necessary to complete a binary search. 
The binary search algorithm starts at the middle of a sorted data set of numbers and eliminates half of the data; this process repeat until the desired value is found or all elements have been eliminated.
AAP-2.P.2
Data must be in sorted order to use the binary search algorithm.
AAP-2.P.3
Binary search is often more efficient than sequential/linear search when applied to sorted
