Sorting Algorithm

This is a sorting algorithm.   It may be applied to a set of data in order to sort it.    
For comparing various sorts, see compare sorts.

Task

Sort an integer array with the   radix sort algorithm.

The primary purpose is to complete the characterization of sort algorithms task.




class Array {
    method radix_sort(base=10) {
        var arr = self.clone
        var rounds = ([arr.minmax].map{.abs}.max.ilog(base) + 1)
        for i in (0..rounds) {
            var buckets = (2*base -> of {[]})
            var base_i = base**i
            for n in arr {
                var digit = (n/base_i % base)
                digit += base if (0 <= n)
                buckets[digit].append(n)
            }
            arr = buckets.flat
        }
        return arr
    }
}
 
for arr in [
    [1, 3, 8, 9, 0, 0, 8, 7, 1, 6],
    [170, 45, 75, 90, 2, 24, 802, 66],
    [170, 45, 75, 90, 2, 24, -802, -66],
    [100000, -10000, 400, 23, 10000],
