What is the average time complexity of accessing an element in an array?

Step 1: Understand what an array is. An array is a collection of items stored at contiguous memory locations.
Step 2: Know that each item in an array can be accessed using an index. The index is a number that tells you the position of the item in the array.
Step 3: Realize that accessing an item by its index means you can directly jump to that position in memory without looking at other items.
Step 4: Since you can access the item directly, the time it takes to get that item does not depend on the size of the array.
Step 5: Therefore, the time complexity for accessing an element in an array is constant, which is represented as O(1).
