Kui suur on juurdepääsu elementile dünaamilises massiivis ajakulu?

In a dynamic array (for example, a slice in Go), access to an element by index has a time complexity of O(1), meaning constant time. This is because elements are stored in a contiguous block of memory, and the address of the required element is calculated directly using the formula:

// Example of accessing a slice element
arr := []int{10, 20, 30, 40}
value := arr[2] // value == 30

Therefore, regardless of the size of the array, access to any element is fast and efficient.
