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 Answer
A 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.

How can one perform a binary search?
One can perform a binary search easily in many different ways. One can perform a binary search by using an algorithm specifically designed to test the input key value with the value of the middle element.
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.
Which data structure, AVL tree or Binary Search Tree, is more efficient in terms of balancing and searching for elements?
An AVL tree is more efficient than a Binary Search Tree in terms of balancing and searching for elements. AVL trees are self-balancing, ensuring that the tree remains balanced after each operation, which results in faster search times compared to Binary Search Trees.
What is the purpose of performing a binary search tree inorder traversal?
Performing a binary search tree inorder traversal helps to visit all nodes in the tree in ascending order, making it easier to search for specific values or perform operations like sorting and printing the elements in a sorted order.
What is the binary search tree worst case time complexity?
Binary search is a log n type of search, because the number of operations required to find an element is proportional to the log base 2 of the number of elements. This is because binary search is a successive halving operation, where each step cuts the number of choices in half. This is a log base 2 sequence.
What assumption about the list is made when binary search is conducted?
Binary search requires that the list be in search key order.
What are the advantages and disadvantages of searching in C programming?
If the data is sorted and every element is directly accessible, then you can perform binary search (see built-in function bsearch), otherwise you have to do linear search (which is slower).
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
Items that are not suitable for a binary search?
The only items suitable for a binary search are those which are in a sorted order.
