Hello! My Perl solution has 46 characters in it and I was wondering how many of you, who have condensed the Perl solution to the same exact character count, have come to the same code.

Long story short, the command:
echo -n ‘mycode’ | md5sum
yelds 22ac70e8aecdb37848cbb481193e99bc on *NIX when run on my solution.

And to test that all is ok:
echo -n ‘mycode’ | wc -c
should output 46

Hello Rogerup! I found several ways to code the solution in C with scanf & printf using 71 characters, but this seems to be the limit… You found the solution with 70 characters. Will you reveal, is your solution still relying on scanf & printf ?

#104

As I said. Without hacking, my limit is 71 characters too. The version with 70 characters is cheating with “system” command. I hope, some day, CodinGame prevent these solutions.
While this does not happen, we can post in this post our best results, using exclusively the commands of each language

Hello guys ! I know that this question has already be asked, but i don’t find the per language ranking… In the header of the leaderboard I only have the choice of the place (world, country, school…), and nothing else…

Edit : I have found. If anyone is searching too, you have to consult the leaderboard from the IDE. Sorry for the disturbance ! :slight_smile:

#106

Some tips for Perl proper: there is no need for ‘split’ directive and no need for comparison operators.

#107

I’m blocked at 93 characters in C. Can you give me some clue about how to do less ?

#108

Variable declarations, logical and ternary operators.

#109

Thank you! I found the solution for C with 68 chars using “system” and “bash” but decided not to sumbit it. Of course, the automatic validator could mark it as “not valid”, but I do not want to take chances of it being valid. I am not still sure how valid the “system cheats” are…

#110

thanks !

#111

36.66°C in your house? :sweat:

#112

My code is failing Validator 1 but passing all others, and it’s the same code I used to solve original puzzle…

#113

Hello.

I joined yesterday codingame to learn groovy. Suddenly I got error h> owever I am sure that code is fine (i’ve checked in IDEA)

def l=[]
n = input.nextInt() // the number of temperatures to analyse
input.nextLine()
temps = input.nextLine() // the n temperatures expressed as integers ranging from -273 to 5526. Feel free to read the input differently.
l+=temps.toInteger()
println([l.findAll({it>0}).min(), l.findAll({it<0}).max()].max().abs())

What might be a problem?

#114

What’s the error message?

#115

There a lot of them. I’ve tried different piece of code. I don’t understand do I need to read values (temps = input.nextLine()) in loop like for(i=0i<n:i++) or not? But it doesn’t work in console, but works in IDEA Intellij. Probably I don’t understand the rules. Which is also possible. Must be value closest to 0.

#116

Ok. I’ve finally found out how to read values from input :slight_smile: temps is String. Now it works except last test when temps is empty.
Elvis doesn;t work for some reason again :slight_smile:

#117

Hello guys !

Does anyone of you have some tips in Ruby ? I’m currently at 71 chars and I’m stuck with this super annoying gets.split.map(&:to_i). Any suggestions for read input more efficiently ?

Thanks :slight_smile:

#118

*$>
…split.min_by{|x|…

#119

I don’t understand why my code which passes all the tests and scores 100% on the easy puzzle fails the first validator of the code golf puzzle.

Any tip for this validator ?

(same as @Inhies)

#120

Obviously your code doesn’t work correctly.
Check other people’s solutions from easy puzzles section to get an idea what might be wrong with your code.

#121

I finally found what was wrong with my solution (without having to check other solutions). Indeed the test “13 -11” would have failed with my previous code !
