Mini programming puzzle/challenge #2

MattDESTROYER · May 22, 2023, 12:57pm

So, a while ago I tried a mini programming puzzle/challenge thingy, and it was largely… a failure Until I ~~nagged~~ asked some to complete it and offered cycles to first one to do so. So I’m going to start this one up front by saying, first to solve gets 500 cycles tipped to a Repl of their choice, second gets 300, third gets 200. In order to make this as fair as possible, no languages like Brainf*** will be allowed, you will need to use a high-level language. Final decision on whether a language/solution is valid are decided by me.

If you complete this challenge (and the top three prizes have not yet been claimed), please private message me your solution to prevent others from stealing it (if you don’t know how or can’t just tell me you think you’ve solved it and I’ll private message you). If all the prizes have been claimed, to prevent spoilers, please use this template if you want to share your solution:

[details="My awesome solution"]
[spoiler]
```javascript <- obviously this will depend on what language you use
console.log("This is my awesome solution!"); <-- your code here
```
[/spoiler]
[/details]

Now to the actual challenge. This is based on one of the weekly coding challenges I participated in on Replit talk a couple of years ago. Your challenge is, without using keywords (def, function, while, etc) with the exception of any keywords to define variables (function definitions are not allowed though, however you could assign a built-in function to a variable), operators (-, *, /, etc) with the exception of addition (usually +) and string concatenation (often + or sometimes .) or data types ("string", true, 123) except within a property accessor, to print the string Hello, world!. Essentially, this will require you to use predefined built-in features of any language of your choice to come up with a hacky solution/trick to print Hello, world!.

I don’t understand. We need to spring Hello world with out console.log, and key words other than the + operator?

DefendyPug · May 22, 2023, 5:21pm

don’t post any possible solutions, here, private message them. shhhhhhh no spoilers.

QwertyQwerty88 · May 22, 2023, 5:35pm

I think so, and no data types ¯\_(ツ)_/¯

MattDESTROYER · May 22, 2023, 8:59pm

console.log is not a keyword, it’s a built-in method, basically, keywords are words that are generally highlighted in blue (although syntax highlighting here makes them purple).

let variable = 123;
while (true) { break; }
if (false) {}

not-ethan · May 22, 2023, 9:00pm

So why can’t I just do

console.log("hello world")

MattDESTROYER · May 22, 2023, 9:01pm

Can’t use data types. This is a very hacky/tricky one to solve

DefendyPug · May 22, 2023, 9:03pm

I dmed you i dont know if you saw it

MattDESTROYER · May 22, 2023, 9:08pm

I’m just going through them now, I’ve already seen one really close attempt

DefendyPug · May 22, 2023, 9:08pm

Oki doki, Im really nervioso

doxr · May 22, 2023, 9:15pm

What if I used jsf___ which has no strings or anything, just a bunch of [ and ] and it doesn’t use concatenation, variables, functions, operators, or data types? It is real Javascript too…

You should add no jsf in the rules

edit: uhhh

MattDESTROYER · May 22, 2023, 9:24pm

I’ve decided you can use variables as it doesn’t allow you to circumvent any of the difficulty of the main challenge.

Firepup650 · May 22, 2023, 9:27pm

What exactly does this mean?

DefendyPug · May 22, 2023, 9:37pm

I’m starting to wonder why people like a post

Why did it get a like?

Firepup650 · May 22, 2023, 9:40pm

For whatever they decide warrants a like.

In this case, I’d assume it’s because they had the same question, or a similar one.

DefendyPug · May 22, 2023, 9:42pm

I’m destroying my brain cells in ways i could not imagine trying to solve the puzzle. I’m not even joking i swear i have a headache now after using up all my brain cpu and ram. Im almost thunked out.

lightdefusion · May 22, 2023, 10:02pm

It took a lot for me to figure out too, but after some time I figured it.

bobbypac · May 22, 2023, 10:03pm

I would think you could create representation of “Hello, World!” in binary or something and log the converted version.

lightdefusion · May 22, 2023, 10:09pm

You are getting very close to a solution

DefendyPug · May 22, 2023, 10:09pm

he didnt message me back yet!!! i didnt get first place didnt I knfswbjfkwjenfksdjvksjdnfisjdvniwjrgw
