Worst case of Quicksort algorithm?
The worst case occurs when data is already sorted where the complexity is O(n^2) instead of the well known O(n log n)
What are the release dates for Worst-Case Scenario - 2010 Downed Powerline Dog Attack 1-2?
Worst-Case Scenario - 2010 Downed Powerline Dog Attack 1-2 was released on: UK: 5 May 2010 USA: 5 May 2010
What is the proper height to mount a thermostat at?
What ever is convenient to see and operate. The thermal sensor however, should always be in the zone it is operating. In the case of a room, about chest to shoulder height.
What do you call two revolving stars of unequal brightness?
Two stars revolving around one another (around their center of mass, to be precise) are called a "binary star". There is no special name for the case that the brightness is unequal; this is actually the usual case.
Where do you send a letter to a Movie director thanking him for an excellent movie?
ANSWER: His agent or google his home address. Worst case, you send it to the talent agency that represents him.
What is the worst case and best case for interpolation search?
binary search
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).
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 height of a binary tree with n nodes in the worst case?
For the height `h' of a binary tree, for which no further attributes are given than the number `n' of nodes, holds:ceil( ld n)
What is best and average case of binary search?
Merge sort is O(n log n) for both best case and average case scenarios.
What is average case complexity of binary search?
Average case complexity for Binary search O(log N). (Big O log n)Habibur Rahman (https://www.facebook.com/mmhabib89)BUBT University Bangladeshhttp://www.bubt.edu.bd/
What is the binary search tree worst case time complexity?
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.
How you can improve search efficiency of sequential search for a sorted file?
When sequentially searching n items, the best-case is O(1) and the worst-case is O(n). But when the items are sorted, binary search will improve efficiency. The best case is still O(1), but worst case drops to O(log n) where log n is the binary logarithm of n. Binary search starts with the middle element of the set. If the set is empty, the item we're looking for does not exist but if the middle element is the item we are looking for then we are done. If not, a simple comparison will tell us in which half of the set to discard (including the middle element). We repeat the process with the remaining half. If there are no elements remaining, the item does not exist.

What is the time complexity for searching an element in an array?
If the array is unsorted, the complexity is O(n) for the worst case. Otherwise O(log n) using binary search.
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.
