Kuidas määrata Go-s elemendi eemaldamise operatsiooni ajakulude keerukus?

In Go, removing an element from a slice usually requires shifting elements, so the time complexity of the operation depends on the position of the element to be removed:

• If an element is removed from the beginning or middle of the slice, all subsequent elements are shifted one position to the left, which results in O(n) complexity, where n is the number of elements after the removed one.

• If an element is removed from the end of the slice, no shifting is needed, and the operation can be close to O(1).

Example of removing an element at index i:

s = append(s[:i], s[i+1:]...)

Here, a new slice is created, into which the elements before and after i are copied, which requires copying elements and has linear complexity depending on the number of copied elements.
