Kuidas määrata aeg, mis kulub elemendi sisestamiseks lõpp-slice'i programmeerimiskeeles?

In the Go language, a slice is a structure that contains a pointer to an array, a length, and a capacity.

Inserting an element at the end of a slice usually occurs through the append operation:

slice = append(slice, newElement)

The insertion time depends on whether the current capacity of the slice is sufficient for the new element:

• If the capacity is sufficient, append simply writes the element into the next free slot — O(1) operation.
• If the capacity is not sufficient, a new array with increased capacity is allocated, old elements are copied, and the new element is added — O(n), where n is the current length of the slice.

Thus, the amortized time for appending at the end of the slice is O(1), although some operations may be more costly due to memory redistribution.
