It sequentially checks one by one of the arrays for the target element until a match is found or until all the elements have been searched of that array. Linear Search is applied on unsorted or unordered lists, when there are fewer elements in a list. In the best-case scenario, the element is present at the beginning of the list and in the worst-case, it is present at the end. We start at one end and check every element until the desired element is not found. Every item is checked and if a match is found then that particular item is returned, otherwise the search continues till the end of the data collection. A linear search, also known as a sequential search, is a method of finding an element within a list. 3. Linear search is also called as sequential search. If the list have large numbers of data then it is insufficient for searching data. Linear search is also called sequential search Linear search is a method for searching a value within a array.
