I have the following code:
var x = Array(1,3,4,4,1,1,3)
var m = Int.MaxValue
x.foreach((x)=>(m = m min x))
I tried to simplify last sentence to:
x.foreach((m = _ min m))
But the interpreter says:
scala> x.foreach((m = _ min m))
<console>:8: error: missing parameter type for expanded function ((x$1) => x$1.min(m))
x.foreach((m = _ min m))
^
I tried to be more explicit about the type:
scala> x.foreach((m = (_:Int) min m))
<console>:8: error: type mismatch;
found : (Int) => Int
required: Int
x.foreach((m = (_:Int) min m))
^
The compiler and I don't understand each other :(
Best regards,
Stan
