However, with some optimizations, we can reduce the time complexity to O (n^2). Once the OBST is constructed, the time complexity of searching for a key is O (log n), the same as for a regular binary search tree. WebBinary search is an efficient algorithm for searching a value in a sorted array using the divide and conquer idea. It compares the target value with the value at the mid-index and repeatedly reduces the search interval by half. The search continues until the value is found or the subarray size gets reduced to 0. bily pepr

"WebWhen you trace down the function on any binary tree, you may notice that the function call happens for (only) a single time on each node in the tree. So you can say a max of k*n operations (k << n, k <= 4 in this case) have been done in this function and so in terms of Big-O has an O(n) complexity. " - Binary search time complexity derivation
