A linear search works by looking at each element in a list of data until it either finds the target or reaches the end. This results in O(n) performance on a given list.
A binary search comes with the prerequisite that the data must be sorted. We can leverage this information to decrease the number of items we need to look at to find our target. We know that if we look at a random item in the data (let's say the middle item) and that item is greater than our target, then all items to the right of that item will also be greater than our target. This means that we only need to look at the left part of the data. Basically, each time we search for the target and miss, we can eliminate half of the remaining items. This gives us a nice O(log n) time complexity.
Just remember that sorting data, even with the most efficient algorithm, will always be slower than a linear search (the fastest sorting algorithms are O(n * log n)). So you should never sort data just to perform a single binary search later on. But if you will be performing many searches (say at least O(log n) searches), it may be worthwhile to sort the data so that you can perform binary searches. You might also consider other data structures such as a hash table in such situations.
binary search runs in O(logn) time whereas linear search runs in O(n) times thus binary search has better performance.

What are the Advantages of binary search on linear search in c?
(i) Binary search can interact poorly with the memory hierarchy (i.e. caching), because of its random-access nature. For in-memory searching, if the interval to be searching is small, a linear search may have superior performance simply because it exhibits better locality of reference. (ii) Binary search algorithm employs recursive approach and this approach requires more stack space. (iii) Programming binary search algorithm is very difficult and error prone (Kruse, 1999).
It is pre requisite for binary search that the list should be in sorted order but if you have a unsorted list then which searching technique would be better binary search or linear search?

What is the height of binary search tree in worst case?
In the worst case a binary search tree is linear and has a height equal to the number of nodes. so h=O(h).
Which is faster binary tree or binary search tree?
A tree doesn't do anything so it has no speed...
How many search techniqe's in data structure?
There are two types of searching technique used in data structure.such as linear and binary search.
Best first search program in c?
The best search programs to attempt writing in C are the following: Linear search (simplest), Binary search (faster) Hash search (fastest).
What are the key differences between an AVL tree and a binary search tree, and how do these differences impact their performance and efficiency in terms of search operations?
An AVL tree is a self-balancing binary search tree where the heights of the two child subtrees of any node differ by at most one. This ensures that the tree remains balanced, leading to faster search operations. In contrast, a binary search tree does not have this balancing property, which can result in an unbalanced tree and slower search times. Overall, AVL trees are more efficient for search operations due to their balanced nature, while binary search trees may require additional operations to maintain balance and optimize performance.
Write a short note on linear search?
Linear search, also known as sequential search, is a process that checks every element in the list sequentially until the desired element is found. The computational complexity for linear search is O(n), making it generally much less efficient than binary search (O(log n)). But when list items can be arranged in order from greatest to least and the probabilities appear as geometric distribution (f (x)=(1-p) x-1p, x=1,2),then linear search can have the potential to be notably faster than binary search.
Which type of search algorithm checks every element on the list in sequence until a matching data is found?
It's called "Linear Search". If the list is sorted, then it is possible to perform more advanced searches like binary search. If the list isn't sorted, then you can either sort the list first and then binary search or simply use a linear search. Linear search is typically a brute force solution when the data isn't "planned" or if the data is stored in a linked list where random access of the values in the list is slow.
What are the key differences between a heap and a binary search tree (BST)?
A heap is a complete binary tree where each node has a value greater than or equal to its children (max heap) or less than or equal to its children (min heap). A binary search tree is a binary tree where the left child of a node has a value less than the node and the right child has a value greater than the node. The key difference is that a heap does not have a specific order between parent and child nodes, while a binary search tree maintains a specific order for efficient searching.

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.
