Choose the scenario(s) when we need to use Linear search?Select one or more:None of these optionsCan use all the timeWhen performing a single search in an un-ordered listWhen the list has only a few elements
Solution
The scenarios when we need to use Linear search are:
-
When performing a single search in an un-ordered list: Linear search does not require the list to be sorted. It starts from the first element and sequentially checks each element in the list until it finds a match.
-
When the list has only a few elements: Linear search can be efficient for smaller lists as it simply involves a sequential scan of the list. For larger lists, other search algorithms like binary search would be more efficient but they require the list to be sorted.
-
Can use all the time: Technically, you can use linear search all the time as it does not have any pre-requisites like the list being sorted. However, it may not be the most efficient search algorithm for all scenarios, especially for larger lists or multiple searches.
So, the correct answer is "When performing a single search in an un-ordered list", "When the list has only a few elements", and "Can use all the time".
