The major limitation of binary search is that there is a need for the sorted array to perform the binary search operation. If the array is not sorted the output is either not correct or maybe after a long number of steps and according to the data structure, the output should come in a minimum number of steps.
Not a limitation of Binary search :Binary search algorithm is not efficient when the data elements are more than 1000.

Limitations of the Binary Search Algorithm

There are several limitations to the binary search algorithm, which is a commonly used algorithm for searching elements in a sorted array. However, one of the limitations mentioned in the options, option D, is not accurate. The correct answer is option 'D' because the binary search algorithm remains efficient even when the data elements are more than 1000. Let's explore the other limitations of the binary search algorithm in detail:

a) It must use a sorted array:
- Binary search requires the array to be sorted in order to work correctly. If the array is not sorted, the algorithm will not produce accurate results.

b) Requirement of sorted array is expensive when a lot of insertions and deletions are needed:
- Binary search is not efficient when it comes to inserting or deleting elements from the array. Whenever an element is inserted or deleted, the entire array must be rearranged to maintain the sorted order. This process can be time-consuming and resource-intensive, especially when there are frequent insertions and deletions.

c) There must be a mechanism to access the middle element directly:
- In order to perform binary search, there must be a way to access the middle element of the array directly. This can be achieved by using the index of the middle element or by using pointers to keep track of the beginning and end of the search range. If such a mechanism is not available, the binary search algorithm cannot be applied.

Correct answer: d) Binary search algorithm is not efficient when the data elements are more than 1000:
- This option is not accurate. The efficiency of the binary search algorithm does not significantly decrease when the number of data elements exceeds 1000. In fact, binary search has a time complexity of O(log n), where n is the number of elements in the array. This means that even for larger arrays, the algorithm can quickly narrow down the search range and find the desired element in a relatively small number of comparisons. Therefore, the binary search algorithm remains efficient regardless of the number of data elements, making option D incorrect.

In conclusion, the binary search algorithm has certain limitations such as the requirement of a sorted array, the expense of maintaining sorted order during insertions and deletions, and the need for a mechanism to access the middle element directly. However, the claim that the algorithm is not efficient when the data elements are more than 1000 is incorrect.

Similar Humanities/Arts Doubts

Directions: Read the following passage carefully:Arbitration has been the toast of the legal community for a long time. It has been long expected that arbitration will replace business litigation to a great extent one day. Lawyers have been encouraging parties to have an arbitration agreement in all their business transaction documents for more than two decades now. However, arbitration has not been proven to be effective too often.A lot of lawyers have begun to re-evaluate if they should put in those arbitration clauses blindly in the agreements they draft. Also, a lot of people who have already put in binding arbitration clauses in their agreements, are finding arbitration very difficult to navigate and too expensive when disputes actually arise.Even after 23 years since the introduction of Arbitration and Conciliation Act of 1996, arbitration seems to be slowly evolving and not really making a dent on pendency of litigation situation and more costly unlike litigation. The Act empowers the arbitrator to terminate the proceedings where without any sufficient cause, the claimant fails to communicate his statement of claim within the stipulated period. If the respondent fails to submit his statement of defence within the predetermined period, the arbitrator shall continue with the proceedings without treating such a failure in itself as an admission of claimants allegations.Would it ever become the mature alternative that Indian businesses can safely rely on for reliable, fast, efficient and cost-effective dispute resolution, especially given the terrible state of civil justice?The BN Srikrishna Committee Report on Institutionalisation of Arbitration Mechanism in India states that a lack of governmental support to promote arbitration is also one of the reasons why arbitration has not become the most preferred way of resolution. The report goes on to suggest that there should be awareness programmes and training to make arbitration a more popular concept. However, such awareness campaigns are very unlikely to attract parties to arbitration given the way it functions at present.Quality of arbitration and arbitrators can often be suspect. The courts have settled the legal proposition that an arbitration agreement is not required to be in any particular form. Courts in India regularly interfere and do not respect party autonomy. The award is expected to be up for appeal or review in the higher courts and that really does not instill confidence in the parties involved in disputes. These factors are putting off parties from adopting arbitration. At present, it appears that only in a handful of matters involving very large claims, arbitration is still viable in India.Q.Which of the following statements would the author mostly agree with?
