For this code
list< int > myList = { 2, 6, 12, 13, 15, 18, 20};
cout << binary_search(myList.begin(), myList.end(), 20) ;
How is the time complexity of binary search is linear?
Time complexity
To perform a Binary search based on Divide and Conquer Algorithm, determination of the middle element is important. Binary Search is usually fast and efficient for arrays because accessing the middle index between two given indices is easy and fast(Time Complexity O(1)). But memory allocation for the singly linked list is dynamic and non-contiguous, which makes finding the middle element difficult.
