Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
For swift, the input for the random tests has been misprogrammed. Here is an example
Optional("l")Optional("c")Optional("p")Optional("s")Optional("k")Optional("l")Optional("r")Optional("y")
as a String. I am guessing it should be "lcpsklry". Somehow in the construction, the "Optional" didn't get
resolved before converting to a String. Instead, it was literally converted. Kind of funny actually.
That did fix it, but code now pretty ugly due rust's strict type checks. Thanks.
In rust, I am getting "solution contains a '-'." failure.
Is the checker picking up the '-' in
fn tadd(x: u32, y: u32) -> u32 {
as a minus sign?
