Great, I will include your answer in my next post! Thanks :)

I will give you a little hint about tools you should use. Take a look on prolog programming language which is great for constraint logic programming :)

Follow me and upvote my post , why ? because i'll do the same

Excellent post..

Submitted. Hope I got it right this time!

Thanks for joining!

Nice and relatively simple logic puzzle. Entered and upvoted

great!

Is it Valid Number ?

meep

| E - N |

What does that mean??? Is it just normal E - N or what else could it mean???

  ·  7 years ago (edited)

that's the absolute sign, a mathematical symbol

that is?

  ·  7 years ago (edited)

it turns negative values to positive. e.g. | -2 | = 2, | 3 | = 3
for more properties of this function you may try to google it

Ahhhh Thanks!

Thank you for the contest! Since I graduated a year ago I don't do many logical thinking problems anymore so this was super fun for me! 😊

glad that you enjoy it! :)

Excellent contest, and send my answer, @kenchung

great, thanks for joining!

I hope to stay in the finalists, the numbers are my passion @kenchung

Someone got it done in minutes?? Not me. Took me about an hour or two.

Submitted answer, upvoted, and resteemed. :)

  ·  7 years ago (edited)

ye I dun think I can do this in minutes too! Never mind the good news is you still got the answer eventually :)

I solved the problem using prolog 😼
Happy to provide the code once the competition ends!
Submitted answer, upvoted, and resteemed.

🐾

great, please do provide your code after the competition ends! I have heard of prolog but forgot how to write already haha

Hi, I posted my prolog solution to the problem as promised 😼

Hope you like it! If you can, please help spread my post to others. I'd like to do this even for future contents if you think this could be a good idea for the people that read and try out these problems.

Thanks

Great thanks! I will include your solution in my next post. A very well-written post!

Love mathematics and problems. Glad that I come across that post. Excellent idea. After like a 15 minutes I participated. :D

Greetings from Turkey!!

Hi there! :) So glad to see this competition has reached the other side of the world haha
Best of luck, wish you can win!
