How do you do binary search in file?
A binary search on a random-access file is performed much in the same way as a binary search in memory is performed, with the exception that instead of pointers to items in memory file seek operations are used to locate individual items within the file, then load into memory for further examination. The key aspects of the binary search algorithm do not depend on the specifics of the set of searchable items: the set is expected to be sorted, and it must be possible to determine an order between any two items A and B. Finally, the binary search algorithm requires that the set of searchable items is finite in size, and of a known size.
What assumption about the list is made when binary search is conducted?
Binary search requires that the list be in search key order.
How can you merge two binary search trees into a single binary search tree?
To merge two binary search trees into a single binary search tree, you can perform an in-order traversal on each tree to extract their elements, combine the elements into a single sorted list, and then construct a new binary search tree from the sorted list. This process ensures that the resulting tree maintains the binary search tree property.
What is the use of binary?
Binary trees are commonly used to implement binary search tree and binary heaps.
A binary search of an orderd set of elements in an array or a sequential search of the elements.Which one is faster?
A binary search is much faster.
What is the binary number for decimal 191?
It is 10111111 in binary. Try a search for '191 to binary'.
Does binary tree and binary search tree same?
no they are not same
Are binary search trees always balanced?
No, binary search trees are not always balanced. Balancing a binary search tree involves ensuring that the height difference between the left and right subtrees of each node is at most 1. Unbalanced binary search trees can lead to inefficient search and insertion operations.
What are the drawbacks of the binary search?
The only drawback I know of is that binary search requires that the list already be sorted. So if you have a really large unsorted list than binary search would not be the best option.
Prove by mathematical induction that the complexity of binary search algorithm is log n?
The complexity of the binary search algorithm is log(n)...If you have n items to search, you iteratively pick the middle item and compare it to the search term. Based on that comparision, you then halve the search space and try again. The number of times that you can halve the search space is the same as log2n. This is why we say that binary search is complexity log(n).We drop the base 2, on the assumption that all methods will have a similar base, and we are really just comparing on the same basis, i.e. apples against apples, so to speak.
How do you print all data in a Binary Search Tree?
By using Depth First Search or Breadth First search Tree traversal algorithm we can print data in Binary search tree.
When is it not recommended to perform the operation of binary search?
In computer science, a binary search or half-interval search algorithm finds the position of a specified value (the input "key") in an array sorted[1][2] into order on the values of the key. At each stage, the algorithm compares the sought key value with the key value of the middle element of the array. If the keys match, then a matching element has been found so its index is returned. Otherwise, if the sought key is less than the middle element's key, then the algorithm repeats its action on the subarray to the left of the middle element or, if the input key is greater, on the subarray to the right. If the array span to be searched is reduced to zero, then the key cannot be found in the array and a special "Not found" indication is returned.A binary search halves the number of items to check with each iteration, so locating the an item (or determining its absence) takes logarithmic time. A binary search is a dichotomic divide and conquer search algorithm.Next AnswerA binary search method requires that the list of items being search should be sorted in ascending (or descending) order. If the search list is not sorted, the binary search method will not work and other search methods will be needed.
