| val truelist = List(true, true, true) | |
| val falselist = List(false, false, false) | |
| val trueFalseList = truelist ::: falselist | |
| truelist.foldLeft(true){ (a,b) => a && b} //true | |
| falselist.foldLeft(true){ (a,b) => a && b} //false | |
| trueFalseList.foldLeft(true){ (a,b) => a && b} //false | |
| //You could also write something like | |
| truelist.forall(_== true) //true | |
