Question

Consider a LIST implemented by array, and containing N elements. The GET operation has worst case time complexity of...

a. O(1)
b. O(log N)
c. O(N)
d. O(N²)

Answer 1

The GET operation on a list implemented by an array has a worst-case time complexity of O(1), due to the direct index-based access that arrays provide.

Step-by-step explanation:

The GET operation for a list implemented by an array that contains N elements generally has a time complexity of O(1). This is because arrays allow random access, meaning that you can directly access any element using its index without having to traverse through other elements. In the worst case, even if the index is known, accessing an element at a specific index is still a direct operation and does not depend on the size of the array, hence the time complexity remains constant, O(1).
