--description--
Given an array with two values, return an array with the values swapped.
For example, given ["A", "B"] return ["B", "A"].
--hints--
array_swap(["A", "B"]) should return ["B", "A"].
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(array_swap(["A", "B"]), ["B", "A"])`)
}})
array_swap([25, 20]) should return [20, 25].
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(array_swap([25, 20]), [20, 25])`)
}})
array_swap([True, False]) should return [False, True].
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(array_swap([True, False]), [False, True])`)
}})
array_swap(["1", 1]) should return [1, "1"].
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(array_swap(["1", 1]), [1, "1"])`)
}})
