Re: [Pharo-users] good game plan for AoC2015 day 4

Hmm, I thought I understand this idea but I do not. I did this in the playground : | answer | answer := Key5Solver new solver.  ^ answer Result class : Object subclass: #Key5Solver     instanceVariableNames: ''     classVariableNames: 'Result'     package: 'AdventOfCode2015-Day4 - Part1' solver : zeros := '000'. zerosSize := zeros  size. count := 0. [        [    candidate := secret , count printString.         ((MD5 hashMessage: candidate) hex first: zerosSize) = zeros     ] whileFalse:         [                count := count + 1.         ].     ] forkAt: 35 named: 'Mining'. but still I do not see the answer. Maybe I have to go for the blocking answer.

Change the Transcript to ```self inform: 'FInished' ```  and then have a different method you call after you see that to return the answer. cheers -ben On Mon, 10 Dec 2018 at 04:16, Roelof Wobben <r.wob...@home.nl> wrote: Hello, I got this code from the discord channel secret := 'abcdef'. zeros := '000'. zerosSize := zeros size. count := 0.

Transcript crShow: 'ANSWER = ' , count printString. ] forkAt: 35 named: 'Mining' but I like that there is no transcipt in the code so my question is how can I change this part( Transcript crShow: 'ANSWER = ' , count printString. ) so it still returns the count. I tried ^count printstring but that is not allowed Regards, Roelof Op 9-12-2018 om 12:29 schreef Roelof Wobben: Helllo, a question about day4 of 2015 is it right that I can only solve this bruteforece so begin at for example 1 , encode it, check for 5 zeros if found then I have found it otherwise increase the counter and do it again https://adventofcode.com/2015/day/4 Regards, Roelof
