In computer science, linear search or sequential search is a method for finding a particular value in a list, that consists of checking every one of its elements, one at a time and in sequence, until the desired one is found.[1]
Linear search is the simplest search algorithm; it is a special case of brute-force search. Its worst case cost is proportional to the number of elements in the list; and so is its expected cost, if all list elements are equally likely to be searched for. Therefore, if the list has more than a few elements, other methods (such as binary search or hashing) will be faster, but they also impose additional requirements. (Source: Wikipedia)
Sequential files do not 'work', they are nothing but sequences of bytes.
Sequential search is the only way to search an unsorted array unless you resort to a multi-threaded parallel search where all threads concurrently search a portion of the array sequentially.
Sequential search of an object with in an array of objects is called as linear search.
As I know the search method depends on your(programmer's) logic. In sequential search it will be better to stop the search as soon as search value encounters or if search value is not in the array then it should stop at the end.
If you're strictly using a sequential search, then the order of the array's content will make no difference. Whether it's in low-high order, high-low order, or randomized, the time complexity for a sequential search will remain O(n).
A binary search is much faster.
N/2
both seach has different algorithem but the complexity will be same...
You will get principal variation from iterative deepening search using sequential moves within the framework. It is important to note that this may slow down the search due to space requirements.Ê
It is a possible solution, yes.
O(N) where N is the number of elements in the array you are searching.So it has linear complexity.
What you're describing is called a sequential search or linear search.
