Difference Between Linear Search and Binary Search
Linear search and binary search are the two methods which are used in arrays for searching the elements. Searching is a process of finding an element within the list of elements stored in any order or randomly. The major difference between linear search and binary search is that binary search takes less time to search an element from the sorted list of elements. So it is inferred that efficiency of binary search method is greater than linear search. Another difference between the two is that there is a prerequisite for the binary search, i.

Binary search tree is a data structure that quickly allows us to maintain a sorted list of numbers. It is called a binary tree because each tree node has a maximum of two children. Basic concepts: Introduction to data structures, classification of data structures, operations on data structures, abstract data type, algorithms, different approaches to design an algorithm, recursive algorithms; Searching techniques: Linear search, binary search and Fibonacci. Binary Search is a searching algorithm for finding an element's position in a sorted array. In this approach, the element is always searched in the middle of a portion of an array.

Introduction to Searching Algorithms
Not even a single day pass, when we do not have to search for something in our day to day life, car keys, books, pen, mobile charger and what not. Same is the life of a computer, there is so much data stored in it, that whenever a user asks for some data, computer has to search it's memory to look for the data and make it available to the user. And the computer has it's own techniques to search through it's memory fast, which you can learn more about in our Operating System tutorial series. Linear search is a very basic and simple search algorithm.
In computer science , a linear search or sequential search is a method for finding an element within a list. It sequentially checks each element of the list until a match is found or the whole list has been searched. A linear search runs in at worst linear time and makes at most n comparisons, where n is the length of the list. Linear search is rarely practical because other search algorithms and schemes, such as the binary search algorithm and hash tables , allow significantly faster searching for all but short lists. A linear search sequentially checks each element of the list until it finds an element that matches the target value.

In computer science, a binary search tree is an ordered data structure that is logically visualized as a tree with a single root node and has two children, one on its right side and the other on its left. These are known as the left child and right child. These children further make subtrees until they reach leaf nodes. It is also often referred to as an ordered binary tree or a sorted binary tree. Similarly, the value of the left child is still lesser than the value of the parent node. In short, nodes in the left subtree have lesser values than the parent node, and nodes in the right subtree have costs higher than the parent node.
