How is the traversal of map elements implemented in the Go language?

In Go, to remove an element from a slice, the operation typically involves slicing and appending, which has a complexity depending on the position of the element:

• Removing an element at the beginning or middle causes all subsequent elements to shift left, resulting in O(n) complexity, where n is the number of elements after the removed element.

• Removing the last element can be close to O(1).

Example of removing element at index i:

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

This creates a new slice by copying elements before and after the index, which is linear in the number of elements being copied.
