When can a binary search not be used?
In case the list of elements is not sorted, there’s no way to use binary search because the median value of the list can be anywhere and when the list is split into two parts, the element that you were searching for could be cut off.
Can we apply binary search on singly linked list?
Given a singly linked list and a key, find key using binary search approach. To perform a Binary search based on Divide and Conquer Algorithm, determination of the middle element is important.
Can binary search be used for sorted linked list?
No we cannot apply binary search algorithm to a sorted linked list, since there is no way of indexing the middle element in the list.
What are the limitations of binary search algorithm?
Binary Search Algorithm Disadvantages-
- It employs recursive approach which requires more stack space.
- Programming binary search algorithm is error prone and difficult.
- The interaction of binary search with memory hierarchy i.e. caching is poor.
What are the advantages and disadvantages of ordered linked list over unordered linked list?
Advantages and Disadvantages of Linked List
- Dynamic Data Structure. Linked list is a dynamic data structure so it can grow and shrink at runtime by allocating and deallocating memeory.
- Insertion and Deletion.
- No Memory Wastage.
- Implementation.
- Memory Usage.
- Traversal.
- Reverse Traversing.
Can we apply binary search on doubly linked list?
1 Answer. It’s technically correct to say that the runtime of binary search on a doubly-linked list is O(n log n), but that’s not a tight upper bound. Using a slightly better implementation of binary search and a more clever analysis, it’s possible to get binary search to run in time O(n).
Which is not a limitation of binary search?
binary search algorithm is not efficient when the data elements are more than 1000.
What are the disadvantages of linked lists?
The linked list requires more memory to store the elements than an array, because each node of the linked list points a pointer, due to which it requires more memory. It is very difficult to traverse the nodes in a linked list. In this, we cannot access randomly to any one node.
Why binary search is used in linked list?
Binary search is used because it has a time complexity of O (N) for a sorted array. If we follow sequential access of Linked List, then it will take O (N) time to find the middle element. With this, the overall time complexity of Binary Search on Linked List will become O (N * logN). This will slower than linear search.
What is the advantage of binary search?
Binary Search is usually fast and efficient for arrays because accessing the middle index between two given indices is easy and fast (Time Complexity O (1)). But memory allocation for the singly linked list is dynamic and non-contiguous, which makes finding the middle element difficult.
How to find the middle element of a singly linked list?
Given a singly linked list and a key, find key using binary search approach. To perform a Binary search based on Divide and Conquer Algorithm, determination of the middle element is important. Binary Search is usually fast and efficient for arrays because accessing the middle index between two given indices is easy and fast(Time Complexity O(1)).
Why must a linked list have to be traversed?
It must be traversed and there is no other way because each element in linked list is not stored contiguously but in random locations and it could be accessed only by traversing the previous element. (The previous element stores the address of the next element)
