Now suppose we are performing both an iterative (loop-based) sequential search and then a recursive binary search on the same list. The sequential search is a standard version that does not take any advantage of the sortedness of the list, simply looking each element in order from the start to the end of the list. Suppose we are searching the list for the value 25 . Also suppose that we are operating on a special computer where reading an element's value in the list (such as examining the value of numbers []) costs 7 units of time; calling any function costs 10 units of time; and all other operations are essentially 0 cost. (Keep in mind that even in a non-recursive search, the cost of making the one and only call to binarysearch still counts in your total.) What is the total "cost" of running a sequential search and recursive binary search over this list of data, searching for the value 25 ? Language/Type: C++ recursion return Related Links: vector Write a recursive function named binarySearch that accepts a reference to a sorted vector of integers and an integer target value and uses a recursive binary search algorithm to find and return an index at which that target value is found in the vector. If the target value is not found in the vector, return -1. The following code shows some example calls and their expected return values: Function: Write a C++ function as described, not a complete program. You should assume that the vector's elements are already sorted; you do not need to handle the case of an unsorted vector. Your function must be recursive and must use a binary search algorithm. Do not use loops or auxiliary data structures
