Is there a better algorithm than binary search?
Interpolation search works better than Binary Search for a Sorted and Uniformly Distributed array. On average the interpolation search makes about log(log(n)) comparisons (if the elements are uniformly distributed), where n is the number of elements to be searched.
Is binary search algorithm important?
Binary Search radically decreases the time required to search for an element in the array and is a very often used algorithm to reduce time complexity in coding questions. The lesson talks about the Trivial Linear Search and developing the intuition with the help of an example.
Why binary search algorithm is best?
Binary search is faster than linear search except for small arrays. However, the array must be sorted first to be able to apply binary search. There are specialized data structures designed for fast searching, such as hash tables, that can be searched more efficiently than binary search.
When should you not use binary search?
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.
What are the advantages of binary search over linear search?
The main advantage of using binary search is that it does not scan each element in the list. Instead of scanning each element, it performs the searching to the half of the list. So, the binary search takes less time to search an element as compared to a linear search.
What is the important factor in binary search?
Binary search requires an order relation by which every element (item) can be compared with every other element in the sense of a total preorder. The part of the element which effectively takes place in the comparison is called its key.
