import { Vector } from "https://deno.land/x/collections@0.12.1/vector.ts";
Returns a shallow copy of a portion of the vector into a new vector.
The start and end represent the index of values in the vector.
The end is exclusive meaning it will not be included.
If the index value is negative, it will be subtracted from the end of the vector.
For example, vector.slice(-2)
would return a new vector
containing the last 2 values.
