A: Sandbox for Proposed Challenges

Manish KunduChallenge There are many numbers which can be expressed as the difference of two squares, or the difference of two cubes, or maybe even higher powers. Talking about squares, there are various ways of writing a number, say 75, as the difference of 2 squares. You can write: 75 = (10)^2 - (5)^2 ...

"appropriate message" - too subjective.

@user202729 So what shall I change that too?
 
user202729
user202729
In my opinion, as many others said, we generally allow flexible input/output format. So I suggest "output all possible pairs of (a, b)".
 
Manish Kundu
Manish Kundu
Okay. Anything else I can improve?
 
user202729
user202729
This way, if there are no solution, just don't output any (a, b) pair (i.e., empty list, or empty output)
In my opinion, the pastebin content is quite short, and that can be included in the challenge itself (what if Pastebin dies? Challenges should be self-contained)

Okay I will remove the pastebin part.

If n = 1, there are infinitely many possibilities. Do you want to allow that?
 
Manish Kundu
Manish Kundu
Thanks for pointing that out. I will update the condition.
hey there.
How does the post look now?
 
user202729
user202729
"anything that you wish to return" ... sounds bad.
Just remove that paragraph entirely.
 
Manish Kundu
Manish Kundu
okay.
How is it now?
 
user202729
user202729
Looks good enough in my opinion. Let me ask on TNB...

What is TNB?

user202729
The Nineteenth Byte.
Codegolf SE general purpose chat room.
 
Manish Kundu
Manish Kundu
Okay.

for inputs 75 and 2, is the output [(10,5),(14,11),(38,37)] okay?
 
Manish Kundu
Manish Kundu
yes
Should I post it on the MS now?
 
totallyhuman
totallyhuman
Seems fine to me

For this particular one, yes. For other challenges, I suggest leaving it in the sandbox for a while.
 
Manish Kundu
Manish Kundu
Okay. I will post my challenges on the sandbox next time before posting.
And do you have any suggestions for a better title? Or the title is apt?
 
user202729
user202729
... I suggest adding "any order of a and b and the pairs are fine".
... wait a minute, I didn't check for duplicates ...
 
Manish Kundu
Manish Kundu
any order of a and b?
 
user202729
user202729
That is, "both (a, b) and (b, a) are fine".
(I'm not very good at English so I may not be able to express my ideas well)
 
Manish Kundu
Manish Kundu
But wouldn't that make a difference? Like (a,b) and (b,a) are different
 
user202729
user202729
2:54 PM
... I think because a < b, any order is fine. You may want to add "but it must be consistent", or restrict to the strict order (b, a).
 
totallyhuman
totallyhuman
it's up to you really but people like flexible output
 
Manish Kundu
Manish Kundu
the current order is a,b because a > b
What do I write in my post?
 
user202729
user202729
The first number in the pair must be larger than the second.
 
Manish Kundu
Manish Kundu
okay yeah that would be enough
And did you find any duplicate of this challenge?
 
user202729
user202729
I think no.
 
Manish Kundu
Manish Kundu
3:01 PM
And any better titles? or should i go with the current one?
 
user202729
user202729
Probably good enough.
 
Manish Kundu
Manish Kundu
So its time to post?
 
user202729
user202729
I think yes.
 
Manish Kundu
Manish Kundu
?
okay.
what should i name the challenge exactly?
okay i am done.

Q: Number As Difference Of Power

Manish KunduChallenge There are many numbers which can be expressed as the difference of two squares, or the difference of two cubes, or maybe even higher powers.

code-golf math number number-theory integer
@totallyhuman what is the input syntax for your code?
 
totallyhuman
totallyhuman
my submission defines an operator (#)
to use it just put a # n where a is the number and n is the power
 
Manish Kundu
Manish Kundu
3:14 PM
okay
@totallyhuman so i write a # n in the input ?
Alright.
works well enough
