# What is a drawback of BST?

## What are advantages and disadvantages of Optimal binary search tree?

Compared to linear search (checking each element in the array starting from the first), binary search is much faster. Linear search takes, on average N/2 comparisons (where N is the number of elements in the array), and worst case N comparisons. Binary search takes an average and worst-case log2(N)log2(N) comparisons.

## What is the limitation of B tree?

Disadvantages: Leaf and non-leaf nodes are of different size (complicates storage) Deletion may occur in a non-leaf node (more complicated)

## What is the disadvantage of binary search algorithm Mcq?

binary search algorithm is not efficient when the data elements are more than 1000. … binary search algorithm is not efficient when the data elements are more than 1000.

## What is the main disadvantage of a binary search compared to a linear search?

It is less efficient in the case of large-size data sets. It is more efficient in the case of large-size data sets. In a linear search, the worst- case scenario for finding the element is O(n). In a binary search, the worst-case scenario for finding the element is O(log2n).

## What are the advantages of BST?

Advantages of using binary search tree The binary search tree is considered as efficient data structure in compare to arrays and linked lists. In searching process, it removes half sub-tree at every step. Searching for an element in a binary search tree takes o(log2n) time.

## What are the worst case and average case complexity 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).

## Which of the following is disadvantage of B plus tree?

✦ (Minor) disadvantage of B+ trees: – extra insertion and deletion overhead, space overhead. and n children.

## What are the advantages of B-tree?

Advantages of B-tree usage for databases keeps keys in sorted order for sequential traversing. uses a hierarchical index to minimize the number of disk reads. uses partially full blocks to speed up insertions and deletions. keeps the index balanced with a recursive algorithm.

## Which is not limitation of binary search algorithm?

binary search algorithm is not efficient when the data elements are more than 1000. Answer» a. binary search algorithm is not efficient when the data elements are more than 1000.

## What is a disadvantage of a linear search?

Disadvantages of a linear search The drawback of a linear search is the fact that its time consuming for the enormous arrays. … Every time a vital element matches the last element from the array or an essential element does not match any element Linear search algorithm is the worst case.

## What are the drawbacks of AVL trees?

Disadvantages of AVL Trees

• As you can see, AVL trees are difficult to implement.
• In addition, AVL trees have high constant factors for some operations.
• Most STL implementations of the ordered associative containers (sets, multisets, maps and multimaps) use red-black trees instead of AVL trees.
