Feb 20, 2023 · Linear Search is defined as a sequential search algorithm that starts at one end and goes through each element of a list until the desired element is found, otherwise the search continues till the end of the data set.

Linear Search is a method for searching an element in a collection of elements. In Linear Search, each element of the collection is visited one by one in a sequential fashion to find the desired element. Linear Search is also known as Sequential Search.
The algorithm for linear search can be broken down into the following steps: 1. Start:Begin at the first element of the collection of elements. 2. Compare:Compare the current element with the desired element. 3. Found:If the current element is equal to the desired element, return true or index to the current element. 4. Move: Otherwise, move to the...
In Linear Search Algorithm, 1. Every element is considered as a potential match for the key and checked for the same. 2. If any element is found equal to the key, the search is successful and the index of that element is returned. 3. If no element is found equal to the key, the search yields “No match found”. For example:Consider the array arr = {1...
In Linear Search, we iterate over all the elements of the array and check if it the current element is equal to the target element. If we find any element to be equal to the target element, then return the index of the current element. Otherwise, if no element is equal to the target element, then return -1 as the element is not found. Below is the ...
Time Complexity: 1. Best Case:In the best case, the key might be present at the first index. So the best case complexity is O(1) 2. Worst Case:In the worst case, the key might be present at the last index i.e., opposite to the end from which the search has started in the list. So the worst-case complexity is O(N) where N is the size of the list. 3....
Unsorted Lists:When we have an unsorted array or list, linear search is most commonly used to find any element in the collection.Small Data Sets:Linear Search is preferred over binary search when we have small data sets withSearching Linked Lists:In linked list implementations, linear search is commonly used to find elements within the list. Each node is checked sequentially until the desired element is found.Simple Implementation:Linear Search is much easier to understand and implement as compared to Binary Search or Ternary Search.Linear search can be used irrespective of whether the array is sorted or not. It can be used on arrays of any data type.Does not require any additional memory.It is a well-suited algorithm for small datasets.Linear search has a time complexity of O(N), which in turn makes it slow for large datasets.Not suitable for large arrays.When we are dealing with a small dataset.When you are searching for a dataset stored in contiguous memory.Linear search is a sequential searching algorithm where we start from one end and check every element of the list until the desired element is found. It is the simplest searching algorithm.
Linear search is a simple yet effective algorithm used to search for a particular element or value in an array or list. It is one of the most fundamental algorithms used in data structures and algorithms with C++.
Linear search, also known as sequential search, is a simple and straightforward searching algorithm. It works by sequentially checking each element in a collection until a match is found or the entire collection has been traversed.
Linear Seach Algorithm: If there are ‘n’ records in a table r(0) to r(n-1) each having a key-value k(0) to k(n-1), the algorithm searches for the required “key” and returns the position ‘i’ of the record r(i) where the “key” is found.

How does linear search work?
Linear search is a type of sequential searching algorithm. In this method, every element within the input array is traversed and compared with the key element to be found. If a match is found in the array the search is said to be successful; if there is no match found the search is said to be unsuccessful and gives the worst-case time complexity.
