C++
please context(explain)
A3 Binary Search is a search algorithm that first checks the middle element of the list. If the search key is found, the algorithm returns the matching location. If the search key is not found, the algorithm repeats the search on the remaining left sublist (if the search key was less than the middle element) or the remaining right sublist (if the search key was greater than the middle element). Can we perform the binary search on the following list? Why or why not? In Binary Search, the decision of discarding one subarray is made in just one comparison. Thus, binary search basically reduces the search space to half at each step. For a 32 element list, if the search key is not found, the search space is halved to have 16 elements, then \( 8,4,2,1 \), and finally none, requiring only 6 steps. Can you explain why the time complexity of the binary earch algorithm is \( O(\log n) \) ?
