Question

Given an array A of size n, we want to access the ith element in the array, 0 1) O(1)

2) O(n)
3) O(log n)
4) O(n²)

Answer 1

Accessing the ith element in an array is done in O(1) time complexity, indicating constant time regardless of the array's size.

Step-by-step explanation:

Accessing the ith element in an array A of size n is a fundamental operation in computer science and is done in O(1) time complexity. This means that no matter how large the array is, the time it takes to access any single element is constant and does not depend on the size of the array.

A direct access operation, like this one, does not require iterating through other elements, as arrays provide random access to their elements. Therefore, the answer to the question is option 1) O(1).

To access the ith element in an array of size n, the time complexity is given by O(1). This means that it takes constant time to access any element in the array, regardless of the size of the array. In other words, the time it takes to access the ith element does not depend on the number of elements in the array.
