I'm trying to improve my J using Advent of Code, but am already a bit
stuck on the second part of day 1. It seems late enough in the day now to
ask this question without spoiling anything.
On the example code one needs to turn the string 'eightwothree' into '8wo3'
I tried the following, which fails because the priority of stringreplace
comes from the left argument ordering:
digs=:'0123456789'
s=:'zero';'one';'two';'three';'four';'five';'six';'seven';'eight';'nine'
substr=:(s,. <"0 digs)
g=:{{ substr stringreplace y}}
g 'eightwothree'
eigh23
How can I get the earliest appearance on the right side to be replaced
first instead?
Thanks,
David
