What I can't get it to do is come back as unbalanced if I'm missing a bracket on the left ((),],{}). I know it's trying to pop from an empty stack but can't figure out how to counter act that. My teacher has it in her Stack class

问题 I have following Scala code sample and I want to know why I get an Error on foldLeft but not with foldRight? val xs = List(1,2,3) val ys = List(4,5,6) (xs foldLeft ys) (_::_) // Error: Value :: is not a member of Int (xs foldRight ys) (_::_) // Res: List(1, 2, 3, 4, 5, 6) I am new to Scala, so please reply as simple as you can.
