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.  
For other sorting algorithms,   see sorting algorithms,   or:

Task

Sort an integer array with the   radix sort algorithm.

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




fcn radixSort(ns){ // ints only, inplace, ns is mutable
   b:=(0).pump(20,List,List().copy);  // 20 [empty] buckets: -10..10
   z:=ns.reduce(fcn(a,b){ a.abs().max(b.abs()) },0); // |max or min of input|
   m:=1;
   while(z){
      ns.apply2('wrap(n){ b[(n/m)%10 +10].append(n) }); // sort on right digit
      ns.clear(); b.pump(ns.extend);		// slam buckets over src
      b.apply("clear");			     // reset buckets
      m*=10; z/=10;			// move sort digit left
   }
   ns
