The linear search problem relates to searching an un-ordered sequence. Because the data is no ordered, we must start at one end of the sequence and inspect each element in turn tunil we find the value we are looking for. If we reach the one-past-the-end of the sequence, the value does not exist. From this we can see that for a set of n elements, the worst case (the element does not exist) is O(n) time while the best case is O(1) time (the element we seek is the first element). Given that there is a 50/50 chance the element we seek will be closer to the start of the sequence than the end, the average seek time is O(n/2).
When a set is ordered we can reduce search times by starting in the middle of the set. In this way, if the element is not found we can eliminate half of the set because we know which half contains the value (if it exists). We repeat the process until we find the value in the middle of the remaining set or the remaining set is empty. The end result is that search times are reduced to a worst case of O(log n), the binary logarithm of n.

∙ 6y agoLinear search means searching elements in the order they appear in the data sequence. Linear search applies to unsorted sequences and has an average time complexity of O(n) for n elements. When the elements are in sorted order, we can use binary search instead, which reduces the average time complexity to O(log n).

The time complexity of the sequential search algorithm is?
O(N) where N is the number of elements in the array you are searching.So it has linear complexity.
What algorithm uses a loop to step through each element of an array starting with the first element searching for a value?
What you're describing is called a sequential search or linear search.
Which search algorithm requires that the arrays contents be sorted?
Binary Search Algorithm
What are the Advantages of binary search on linear search in c?
(i) Binary search can interact poorly with the memory hierarchy (i.e. caching), because of its random-access nature. For in-memory searching, if the interval to be searching is small, a linear search may have superior performance simply because it exhibits better locality of reference. (ii) Binary search algorithm employs recursive approach and this approach requires more stack space. (iii) Programming binary search algorithm is very difficult and error prone (Kruse, 1999).

Which type of search algorithm checks every element on the list in sequence until a matching data is found?
It's called "Linear Search". If the list is sorted, then it is possible to perform more advanced searches like binary search. If the list isn't sorted, then you can either sort the list first and then binary search or simply use a linear search. Linear search is typically a brute force solution when the data isn't "planned" or if the data is stored in a linked list where random access of the values in the list is slow.
