Occasionally we see StackOverflow Java questions (and C or C++ questions) that ask what something like this: i += a[i++] + b[i--]; evaluates to ... for some known initial states of i, a and b. Generally speaking: for Java the answer is always specified1, but non-obvious, and often difficult ...

Let A and B be two matrices of same dimension. The operators +,-,/,*,^ when used with matrices of same dimension perform the required operations on the corresponding elements of the matrices and return a new matrix of the same dimension. These operations are usually referred to as element-wise opera...

Haskell Wiki has an example of a non-parametric parameter of a type function: type family Inspect x type instance Inspect Age = Int type instance Inspect Int = Bool Here x is non-parametric because to determine the outcome of applying Inspect to a type argument, the type function must insp...

An example of a parametric parameter of a type function: data List a = Nil | Cons a (List a) type family DoNotInspect x type instance DoNotInspect x = List x Here x is parametric because to determine the outcome of applying DoNotInspect to a type argument, the type function do not need to in...
