If you are curious, compare this to my solution.

thing to note is that value is a keyword, so I often try to avoid using it

another option is to just return rather than keeping a character result value :)

This isn't always true
solution('abcc', 'bc') shoud return false, but will return true with your solution
A test scenario should be added for c# for this case

c# still is not able to be completed because of rounding

good, using linq :)

You can click "View Solution" to see what I did

This is an issue for c#, I checked and it isn't for java. I believe just c# needs to be fixed.

Look at my solution... yeah, this does compile and passes the final check. I think what they wanted was what I did. I know, silly.
