Forgive me if this is trivial, I’m just starting out.

Construct a function to return the default value of any type:

f(x) = x+2
p(y) = if(y>2) true else false

val subjectpairs = IndexedSeq((8,0),(3,4),(0,9),(6,1)) val priors = subjectpairs.map { case( f,_) => f}.filter{ _ >0.0} val posts = subjectpairs.map { case( _,l) => l}.filter{ _ >0.0} This creates 2 sequences from the first , with the first and second members of tuples as non-zero respectively. However , this needs 2 iterations of the source sequence […]

I have some nested case classes that may look like the following:

I am executing

I have a list in scala , where the structure of the list is :

I have a function that needs to be pass in a long value.
As code block example below:

Given a class with a function:
