Which of the following algorithms will run in constant time?(1 point)

3 answers

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:

  1. Accessing an element in an array by index (e.g., array[i])
  2. Returning a fixed value or performing a simple mathematical operation (e.g., addition, subtraction)
  3. 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.

What the answer

To determine which algorithm runs in constant time (O(1)), I would need a list of specific algorithms you are considering. Constant time algorithms are those whose execution time is fixed and does not change regardless of the input size.

Here are some general examples:

  1. Accessing an element in an array using an index (e.g., array[5]).
  2. Checking if a number is even or odd (e.g., number % 2 == 0).
  3. Returning the first element of a list or array (e.g., list[0]).
  4. Performing simple mathematical operations (e.g., x + y, x * y).

If you provide the specific options or algorithms you're inquiring about, I can help you identify which one(s) run in constant time.
