Function permutations

permutations<T>(inputArray): T[][]
Builds all possible orders of all elements in the given array Ignores equality of elements, meaning this will always return the same number of permutations for a given length of input.
Type Parameters
- T
  The type of the elements in the array.
Parameters
- inputArray: Iterable<T, any, any>
  The array to build permutations from.
Returns T[][]
An array of all possible permutations of the given array.
Example: Basic usage
```
import { permutations } from "@std/collections/permutations";
import { assertEquals } from "@std/assert";

const numbers = [ 1, 2 ];
const windows = permutations(numbers);

assertEquals(windows, [
  [ 1, 2 ],
  [ 2, 1 ],
]);
```
