    Welcome to PPCG! This is the start of a good question. I couldn't find a duplicate from a quick search, though I might be mistaken. One thing I'd suggest is to specify the input and output. I assume that the input is an integer N. Is the output a list of tuples, a list of strings, should it be printed? Does it need to be separated by a comma?

    Are we allowed to return a list instead of printing them? Is any order acceptable (i.e. [[0,0],[0,1],[0,2],[1,0],[1,1],[1,2],[2,0],[2,1],[2,2]] instead of what you have above)? Can the output have 1-indexed coordinates instead of 0-indexed?

    Can't decide whether this is a dupe of this (just hardcode $n=2$) or this (just duplicate the argument instead of taking two distinct), but probably both.

I'm by no means a C programmer (or C golfer), but I thought I'd give it a try. Should the main be included in the byte count?

  • 51 bytes :) (And no, main method doesn't have to be included. For Java, C, C#, etc. etc. we allows functions instead of full programs, since full programs are quite verbose and doesn't add anything to the actual solution.)

  • Btw, to have the exact same order for each coordinate as in the input (ordered by y-then-x instead of x-then-y), the i++/n,i%n should be i++%n,i/n. :)

  • @Sumner18 You can't be as golfy if you don't understand a big chunk of the language, so it pays to read the docs! there are a few workhorse functions like match and which. which in particular has an arr.ind argument, so looking at the documentation for which, we see a note in the Details under .dimnames about passing to the arrayInd function!

L<ãí',ý»


Exactly as the challenge description: prints the 0-indexed coordinates ordered by y-then-x comma- and newline-delimited to STDOUT.



Try it online.



Explanation:





L          # Create a list in the range [1, (implicit) input]
# i.e. 3 → [1,2,3]
< # Decrease each by 1 to make the range [0, input)
# i.e. [1,2,3] → [0,1,2]
ã # Create each possible pair with itself
# i.e. [0,1,2] → [[0,0],[0,1],[0,2],[1,0],[1,1],[1,2],[2,0],[2,1],[2,2]]
í # Reverse each pair so they're sorted by y-then-x instead of x-then-y
# i.e. [[0,0],[0,1],[0,2],[1,0],[1,1],[1,2],[2,0],[2,1],[2,2]]
# → [[0,0],[1,0],[2,0],[0,1],[1,1],[2,1],[0,2],[1,2],[2,2]]
',ý '# Join each pair with a space delimiter
# i.e. [[0,0],[1,0],[2,0],[0,1],[1,1],[2,1],[0,2],[1,2],[2,2]]
# → ["0,0","1,0","2,0","0,1","1,1","2,1","0,2","1,2","2,2"]
» # And then join everything with a newline delimiter (and output implicitly)
# i.e. ["0,0","1,0","2,0","0,1","1,1","2,1","0,2","1,2","2,2"]
# → "0,0n1,0n2,0n0,1n1,1n2,1n0,2n1,2n2,2"







05AB1E, 2 bytes






Returns a list of 1-indexed coordinates ordered by x-then-y.



Try it online.



Explanation:





L     # Create a list in the range [1, (implicit) input]

ã # Create each possible pair with itself (and output implicitly)
# i.e. [1,2,3] → [[1,1],[1,2],[1,3],[2,1],[2,2],[2,3],[3,1],[3,2],[3,3]]

  • @maxb I've added an explanation to my post now. L is a 1-indexed list in the range [1,n] (where n is the implicit input). I've made it 0-indexed in my 8-byte answer with the < (decrease by 1).

    Welcome to the site! Unfortunately, assuming input is in a predefined variable is not a standard form of input. You could add a console.readline() or however that's supposed to work (I'm not too familiar with C#) or submit a function instead.

    Hi, welcome to PPCG! We allow either functions or full programs as answers (yours is currently more like a snippet), and all imports add to the byte-count. Which means your current answer should be l=>{for(var j=0;j<l*l;j++)System.Console.Write($"{j%l},{(int)j/l}n");} instead (71 bytes). However, you can golf 6 bytes by changing (int)j/l to j++/l and remove the j++ like this: l=>{for(int j=0;j<l*l;)System.Console.Write($"{j%l},{j++/l}n");}. Try it online.

                    Saved 32 bytes and fixed output order thanks to Kevin Cruijssen.

                    Try it online!



                    I'm by no means a C programmer (or C golfer), but I thought I'd give it a try. Should the main be included in the byte count?

                    Where do you hear about all of these functions in R? I've never even used arrayInd before, but I feel like it could be useful in a lot of things!

                    @Sumner18 You can't be as golfy if you don't understand a big chunk of the language, so it pays to read the docs! there are a few workhorse functions like match and which. which in particular has an arr.ind argument, so looking at the documentation for which, we see a note in the Details under .dimnames about passing to the arrayInd function!

                    • @maxb I've added an explanation to my post now. L is a 1-indexed list in the range [1,n] (where n is the implicit input). I've made it 0-indexed in my 8-byte answer with the < (decrease by 1).

                      Welcome to the site! Unfortunately, assuming input is in a predefined variable is not a standard form of input. You could add a console.readline() or however that's supposed to work (I'm not too familiar with C#) or submit a function instead.

                      Hi, welcome to PPCG! We allow either functions or full programs as answers (yours is currently more like a snippet), and all imports add to the byte-count. Which means your current answer should be l=>{for(var j=0;j<l*l;j++)System.Console.Write($"{j%l},{(int)j/l}n");} instead (71 bytes). However, you can golf 6 bytes by changing (int)j/l to j++/l and remove the j++ like this: l=>{for(int j=0;j<l*l;)System.Console.Write($"{j%l},{j++/l}n");}. Try it online.

                                            Pepe, 88 bytes



                                            I've never done 2D iterating in Pepe before and it doesn't seem to work pretty well due to labels being dynamic. There's quite a lot of two byte commands to avoid moving the pointer.
