I asked this question a few days back.
An argument with my friend over $\bigcup [a+\frac{1}{n},b]$
I had asked this question to know whether I was right in my approach, which other users approved to be correct. Now as you can see I have two answers to the question.
On what basis should I mark the question solved. I mean, ofcourse, the question was never unsolved, (and leaving a question with a solution marked unsolved doesn't seem right), but which answer do I mark as accepted answer? Thanks. :)
