Can I publish a paper that doesn't have a specific question to answer? I have created a new data structure, and I intend to submit a paper about it to an ACM conference later this year. However, in writing the paper, I realize there is no specific "question" the research answers. I was simply curious if such a structure could be created. Can I simply write the paper, describe the structure and how it works, and then give a pseudocode example and perhaps comparisons to other data structures? The structure has some rather interesting properties, and I can see specific applications for it in statistical analysis. But beyond that, as far as I can tell, it's just a neat structure with some weird properties.
I would suggest that you investigate those interesting properties further and then have a paper along the lines of "this structure has this useful property, more-so (or less-so) than these other structures." That is justify why someone would actually use this structure. 

Think about it from the editors' point of view. Why should this paper be published? If you can't provide an answer with a straight face then maybe you should wait until there is a purpose for it.
