An algorithm runs in constant time, often denoted as O(1), when its execution time does not depend on the size of the input. Examples of such algorithms typically include:
- Accessing an element in an array by index (e.g.,
array[i]
) - Returning a fixed value or performing a simple mathematical operation (e.g., addition, subtraction)
- Checking if a number is even or odd
If you have specific algorithms or options in mind, please provide them, and I can help you determine which, if any, run in constant time.
