Mmmh, Safari refuses to show the images in the description of this kata due to a certificate issue. When I open it in Chrome it seems the formulas did not render very well. Deciphering the formula seems to be the hardest bit...

So, I read in the comments below that all '\n' should be preserved.
When I test my solution, the first one it fails on is:

stripcomments("stripcomments(str, ms) = nomorecomments(please())\n# Julia comments!\nstripcomments("I hope it works") # but I bet it won't\n", ["#"]) --> "stripcomments(str, ms) = nomorecomments(please())\nstripcomments("I hope it works")"

Expected: "stripcomments(str, ms) = nomorecomments(please())\nstripcomments("I hope it works")"
Occurred: "stripcomments(str, ms) = nomorecomments(please())\n\nstripcomments("I hope it works")"

So apparently I need to completely remove the line "# Julia comments!\n"?

But if I remove the empty lines completely, I fail on another test case. I see 13 people have completed this in Julia, so apparently I'm interpreting something incorrectly. Does anyone know what I'm doing wrong?

Oh come on, format of the input could not be any simpler :) Parsing it is close to trivial for a kata of this rank.

I want to like this kata. But I don't understand why I have to manipulate strings and deal with newline characters in the input. It distracts from the problem at hand. (C++)
