Array#minmax was not implemented so it was deferring to Enumerable#minmax, which iterates over the array. By implementing Array#minmax, with #min and #max, performance is improved.
`Array#minmax` doesn’t support the `n` parameter in the same way that `#min` and `#max` do, so we shouldn’t accept it here. Before: ``` >> array = (1..10).entries => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] >> smallest, largest = array.minmax(3) => [[1, 2, 3], [10, 9, 8]] >> smallest => [1, 2, 3] >> largest => [10, 9, 8] ``` After: ``` >> array = (1..10).entries => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] >> smallest, largest = array.minmax(3) ArgumentError (wrong number of arguments (given 1, expected 0)) ```
