What are the average case complexities of a binary search tree?
Binary search’s average and worst case time complexity is O ( log n ) O(\log n) O(logn), while binary search tree does have an average case of O ( log n ) O(\log n) O(logn), it has a worst case of O ( n ) O(n) O(n).
What is average case in binary search?
The average cost of a successful search is about the same as the worst case where an item is not found in the array, both being roughly equal to logN. So, the average and the worst case cost of binary search, in big-O notation, is O(logN).
What is the average and worst case complexity of binary search algorithm?
Average Case Time Complexity of Binary Search: O(logN) Worst Case Time Complexity of Binary Search: O(logN)
What is the average case complexity of binary search using recursion?
6. What is the average case time complexity of binary search using recursion? Explanation: T(n) = T(n/2) + 1, Using the divide and conquer master theorem. 7.
What is the average case time complexity of binary search tree using recursion?
O(n2)
What is the average case complexity of quicksort?
O(n log n)
Average-case analysis To sort an array of n distinct elements, quicksort takes O(n log n) time in expectation, averaged over all n! permutations of n elements with equal probability.
What is the average case complexity of linear search algorithm?

Binary search algorithm/Best complexity
What is the average case time complexity of binary search using recursion 2 points?
What is the best case complexity of binary search?
What is the average case time complexity for finding the height of the binary search tree?
Searching: For searching element 1, we have to traverse all elements (in order 3, 2, 1). Therefore, searching in binary search tree has worst case complexity of O(n). In general, time complexity is O(h) where h is height of BST.
