How to determine the time complexity of deleting an element from a slice in Go?

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 being removed:

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

• If an element at the end of the slice is removed, no shift 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, copying elements before i and after i, which requires copying elements and results in linear complexity proportional to the number of elements copied.
