Was working on a harder question and wanted to save my progress.
I copy and pasted my code from hackerrank into TextEdit and continued to work on the problem.
With 3 minutes to spare and no luck, I decided to revert to my last working solution. I copy and pasted my code from TextEdit into hackerrank.
For some reason, TextEdit replaced every ' ' character with '\u00a0'. My code would not compile, and I couldn't command F for that character in TextEdit.
Failed that question because of TextEdit. I am wiping textedit from my computer and from now on, will only save to a text editor that does not try to format text. FML.
