## What is the average case for binary search?

O(logN)
The dominant term is N * logN / (N+1) which is approximately logN. Therefore, Average Case Time Complexity of Binary Search is O(logN).

## What is the average case occur in the linear search when?

Explanation: The average case occurs in the Linear Search Algorithm when the item to be searched is in some where middle of the Array. The best case occurs in the Linear Search Algorithm when the item to be searched is in starting of the Array.

What is average case analysis?

Average-case analysis requires a notion of an “average” input to an algorithm, which leads to the problem of devising a probability distribution over inputs. Alternatively, a randomized algorithm can be used. The analysis of such algorithms leads to the related notion of an expected complexity.

O(n2)

### What are the worst case and average case of 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 the best case of binary search?

O(1)Binary search algorithm / Best complexity

## What is the average case complexity of linear search Mcq?

Explanation: The complexity of linear search as the name suggests is O(n) which is much greater than other searching techniques like binary search(O(logn)).

## What is the best case for linear search?

In linear search, best-case complexity is O(1) where the element is found at the first index. Worst-case complexity is O(n) where the element is found at the last index or element is not present in the array.

How is average case calculated?

Average Case Analysis (Sometimes done) In average case analysis, we take all possible inputs and calculate computing time for all of the inputs. Sum all the calculated values and divide the sum by the total number of inputs.

### What is the average case efficiency?

Best Case Efficiency – is the minimum number of steps that an algorithm can take any collection of data values. Smaller Comparisons.In Big Oh Notation,O(1) is considered os best case efficiency. Average Case Efficiency – average comparisons between minimum no. of comparisons and maximum no.

### What are the worst case and average case complexity of binary search?

What is the best-case and worst case for binary search?

For a binary search, the best-case occurs when the target item is in the beginning of the search list. For a binary search, the best-case occurs when the target is at the end of the search list. For a binary search, the worst-case is when the target item is not in the search list.
