A linear search algorithm, which involves checking each element of a list sequentially to find a target value, has the following complexities:
- Time Complexity: O(n) - In the worst case, you may need to check every single element in the list before finding the target or concluding that it's not present.
- Space Complexity: O(1) - The space used by the algorithm does not scale with the input size since it only requires a fixed amount of space for variables (for example, to store the index or the target).
Therefore, among the options given, none exactly match the correct complexities for a linear search. The complexities are properly summarized as:
- Time Complexity: O(n)
- Space Complexity: O(1)
