Question

I am working on a algorithm but there is a note about a selector. I am not sure what this means but the research paper I am working says:

δ () is a selector, i.e. δ (x) =1 if x>0, else
δ (x) = 0 ;

How does one code this using pseudo code, c++, or Java?
Thanks

δ () is a selector, i.e. δ (x) =1 if x>0, else δ (x) = 0

You just need an if

In pseudocode:

delta = function(x)
      {
      if (x > 0)
          return 1
      else
          return 0
      }
