Orderedsearch

Ordered search, also known as sequential search or linear search, is a fundamental algorithm used to find a specific element within a list or array. It operates by examining each element in the data structure one by one, in the order they appear, until the target element is found or the end of the list is reached.

The process begins with the first element of the ordered sequence. If this element matches the target value, the search is successful, and the algorithm typically returns the index or position of the found element. If the current element does not match, the algorithm moves to the next element and repeats the comparison. This continues iteratively.

Should the algorithm traverse the entire list without finding the target element, the search is considered unsuccessful. In such cases, it usually returns a special value, such as -1 or null, to indicate that the element is not present in the list.

Ordered search is straightforward to implement and does not require the data to be sorted. However, its efficiency is dependent on the position of the target element. In the worst-case scenario, where the element is at the end of the list or not present at all, the algorithm must examine every single element. This results in a time complexity of O(n), where 'n' is the number of elements in the list. For large datasets, more efficient search algorithms like binary search, which requires a sorted list, are often preferred.
