What is the time complexity of accessing the nth element on an unsorted array?O(n!)O(2^n)O(1)O(n)O(nlog(n))O(n^2)O(log(n))

Break Down the Problem

1. We need to determine the time complexity of accessing the nth element in an unsorted array.

Relevant Concepts

2. In an unsorted array, each element can be accessed directly using its index. This allows for efficient retrieval of elements.

Analysis and Detail

3. When accessing an element in an array using its index, the operation is performed in constant time. This is because arrays allow for direct indexing, meaning that the position of the nth element is calculated instantly using its index.

Verify and Summarize

4. Given that accessing an element by its index does not depend on the size of the array (n), the time complexity for accessing the nth element is $O(1)$.

Final Answer

The time complexity of accessing the nth element in an unsorted array is $O(1)$.
