WebFeb 8, 2009 · For a non-self-balancing tree (possible but unusual for a search tree), worst case is O(n), which is for the degenerate binary tree (a linked list). In this case, you have to search, on average, half the list before finding your desired element. Best case is O(log 2 n) for a perfectly balanced tree, since you cut the search space in half for ... WebAug 2, 2024 · Average case complexity of Binary Search The average case is also of O(log(n)). Space complexity of Binary Search Binary Search requires three pointers to elements (start, middle and end), regardless of the size of the array.
