Re: I need sorting help

Using my quick-intuition, are these methods sorting on the earliest number
withing the string, ignoring the non-digits?

$ raku -e '.say for <bk10 bk34 bk2 bk1>.sort: {m/ \d+ /.Int}'
$ raku -e '.say for <bk10 bk34 bk2 bk1>.sort: +*.match: / \d+ /'

let's see

$ raku -e '.say for <say31 what20 the30letters40 does2 not3 it1
matter10>.sort: {m/ \d+ /.Int}'
it1
does2
not3
matter10
what20
the30letters40
say31

What's been interesting about this thread is not only the variety of
solutions, also that the solutions are for two different questions-

how to sort by alpha & numeric segments (b3b, a1a, c20c) =>  (a1a, b3b, c2c)
how to sort by a numeric segment only (b3b, a1a, c20c) =>  (a1a, b3b, c20c)
