Bead sort

func beadsort(arr) {

    var rows = []
    var columns = []

    for datum in arr {
        for column in ^datum {
            ++(columns[column] := 0)
            ++(rows[columns[column] - 1] := 0)
        }
    }

    rows.reverse
}

say beadsort([5,3,1,7,4,1,1])

Output:

[1, 1, 1, 3, 4, 5, 7]
