jasondavies / radixsort.js Goto Github PK

I have started writing a benchmark for sorting methods. I included your NPM package radixsort in this benchmark. After the benchmark has run, I do a sanity check on the output. I consistently get the wrong output with random inputs (I started by copying the approach you had taken in your tests) . The output is sorted, however, it does not correspond to the input. I have checked a bunch of other sorting functions that yield the correct output. Did I do something wrong?

@jasondavies thanks for the awesome module, its performance is mind-blowing! Still scratching my head over the following issue though:

In most algorithms, you don't just sort a set of numbers without context — usually you sort numbers associated with some additional data. For example, when sorting 2d points by x, you can't use radixSort in the current form because you also need to access y in addition to x in resulting x-sorted points.

What's the easiest way to modify this module to support this kind of use case? For example, could we additionally generate an array associating each sorted element wth original array through indices?
