Binary search is a log n type of search, because the number of operations required to find an element is proportional to the log base 2 of the number of elements. This is because binary search is a successive halving operation, where each step cuts the number of choices in half. This is a log base 2 sequence.

What is the height of binary search tree in worst case?
In the worst case a binary search tree is linear and has a height equal to the number of nodes. so h=O(h).
What is the worst case and best case for binary search?
The best case for a binary search is finding the target item on the first look into the data structure, so O(1). The worst case for a binary search is searching for an item which is not in the data. In this case, each time the algorithm did not find the target, it would eliminate half the list to search through, so O(log n).
Complexity of linear search?
the compexity of linear search in worst case is f(n) = n+1
What is Efficiency of Binary Search tree operations?
If it is an unbalanced binary tree, O( ln( n ) / ln( 2 ) ) is best-case. Worst case is O( n ). If it is balanced, worst case is O( ln( n ) / ln( 2 ) ).
What is the worst case and best case time complexity of heapsort?
The best and worst case time complexity for heapsort is O(n log n).
What is the worst-case time complexity of quicksort?
The worst-case time complexity of quicksort is O(n2), where n is the number of elements in the array being sorted.
What is best and average case of binary search?
Merge sort is O(n log n) for both best case and average case scenarios.
Advantages of binary search over sequencial search?
Linear search takes linear time with a worst case of O(n) for n items, and an average of O(n/2). Binary search takes logarithmic time, with a worst and average case of O(n log n). Binary search is therefore faster on average.
What is the worst case time complexity of heapsort?
The worst case time complexity of heapsort is O(n log n), where n is the number of elements in the input array.
