| Oct 13, 2014 at 12:48 | comment | added | Federico Poloni | @RobertBryant Thanks for your consideration, but I encourage you to undelete it, I think it was useful. There is nothing wrong with two answers that give different views and information. People can upvote us both. :p | |
| Oct 13, 2014 at 12:42 | comment | added | Robert Bryant | @FedericoPoloni: I deleted it when I saw that you had already posted an answer. (You must have posted after I started typing, because I didn't see your answer until I hit 'post'.) I didn't feel that my answer really added anything after yours, so I deleted it to keep people from voting for it and thus drawing votes from your prior answer. | |
| Oct 13, 2014 at 12:28 | comment | added | Federico Poloni | @RobertBryant I saw your answer only briefly -- why did you delete it? It looked correct to me, and it added some insight on the origin of the solution which my answer currently lacks. | |
