The purpose of searching algorithms is to find out whether a specific element is present in a data structure or not. If the element can be found, an operation relevant to it will be performed. According to the traversing mechanism, search algorithms can be based on linear search or binary search. The primary difference between linear search and binary search is that while the former depends on sequential comparison, the latter follows the divide-and-conquer rule to find an element.

Understanding the difference between linear search and binary search is crucial to figure out which method to use for searching an element. Dive into this article to gain details about the difference between linear search and binary search.

Linear search is a simple searching algorithm based on a sequential model. Unlike binary search, the linear search algorithm checks every item in a list to find the required element. Like stacks in data structures, a linear search algorithm will check elements in a particular order. A linear search, sometimes referred to as a sequential search and is suitable for searching over a small array or an unsorted array.

When the element you are looking for is in the first position of the data structure, only one comparison would be sufficient. But an N number of comparisons will be required to find elements in the last position.

Binary search is an algorithm for finding an item from a sorted list of items. It is called binary search because it splits the array into two halves as part of the algorithm. It is also known as half-interval search, logarithmic search, or binary chop.

When you compare linear search and binary search, the binary search seems to be faster. But a significant difference between linear search and binary search is that you need to sort the items in a list before using the binary search algorithm. Click on this to understand more about sorting in data structures.

Basically, the binary search can help you find any item by comparing the middlemost item of the collection. Therefore, one massive difference between linear search and binary search is that binary search can be completed within a short span.** **

Several exciting data science projects for beginners demand the application of searching algorithms. Data analytics professionals often need to use linear vs. binary search for operations. You can understand everything about data science and analytics here: Data Science Vs. Data Analytics: Key Difference Between Data Science & Data Analytics. But if you want to understand the difference between linear search and binary search, keep scrolling down.

The difference between linear search and binary search is that linear search is simpler to use and is less complex whereas the binary search is comparatively complicated.

A business analyst course will offer more details about the simplicity and complexity of linear search vs. binary search.Binary search can be implemented of only one-dimensional array whereas, Linear search can be used on both single and multidimensional array.

You can check the real-time application of data structures here.

Comparison Factor |
Linear Search |
Binary Search |
---|---|---|

Algorithm | Sequential searching | Divide and conquer approach |

Sorted List | Not mandatory | mandatory |

Working | Checks every element sequentially as long as a match can’t be found | Divides a list in two halves from the middle on every iteration as long as the position of a target value cannot be spotted |

Implementation | Useful for data structures that enable traversal in a single way like arrays and linked list | Useful only for data structures supporting two way traversal |

Simplicity and Complexity | Simple and less complex | More complicated than linear search |

Time Required | 0 (n) | 0 (log n) |

Efficiency | Not useful for large datasets | More efficient for finding elements in large datasets |

Best Case | When an element can be found in the first position of an array | When an element can be found at first split, the middle element of an array |

Also Called | Sequential search | Half-interval search or logarithmic search |

FAQs

Which is faster, linear, or binary search?

If you compare linear search and binary search, binary search will prove to be faster and more efficient, particularly for larger data sets.

What is the difference between linear search and binary search?

The difference between linear search and binary search is that binary search does not scan every element in a list like linear search. Linear search is simpler while binary search is faster.

Which search algorithm is best?

In linear search vs. binary search, binary search is better. A major difference between linear search and binary search is that binary search can be more useful for searching elements in large data structures.

Why is binary search better than linear?

When you compare linear search vs. binary search, you will find binary search is better for finding elements in large data structures. The binary search uses the divide-and-conquer approach to find elements faster.

Where is linear searching used?

linear search is great for performing a single search in an unordered list. One of the prominent differences between linear search and binary search is that linear search can only be used in a list with few elements.
