The algorithm that will run in constant time among the options listed is:

accessing an element of an array

Accessing an element in an array by its index is a constant time operation, denoted as O(1), because it takes the same amount of time regardless of the size of the array.

The other options are not constant time:

  • Traversing an array takes O(n) time, where n is the number of elements in the array.
  • Sorting an array typically takes O(n log n) time (for efficient sorting algorithms).
  • Binary search on a sorted array runs in O(log n) time.

The evaluation of an algorithm’s performance and efficiency is known as:

asymptotic analysis

Asymptotic analysis assesses the behavior of an algorithm as the size of the input grows, focusing on the worst-case, average-case, or best-case scenarios, typically expressed in Big O notation.

The options "basic operations," "solution costs," and "hash table" do not correctly describe the concept of evaluating an algorithm's performance and efficiency.

Which of these matches keys to values and stores and stores them?(1 point)
Responses

hash table

The option that matches keys to values and stores them is:

hash table

A hash table is a data structure that uses a hash function to map keys to their associated values, allowing for efficient data retrieval. The other options do not specifically refer to the concept of mapping keys to values in the same way.
