Consider the following Haskell data type and function, and answer the questions below: data T a = LF a|N(Ta) (Ta) (Ta) fg (LFx)=xfg (Nlcr) = g(fgl) (g(fgc) (fgr)) (a) What does it mean for a data type to be polymorphic? (b) Is the data type T polymorphic? (c) What is the use of the identifier a in the Haskell code? (d) If possible, give an example of a value that has type T Int. (e) If possible, give an example of a value that has type T Char. 25 (f) Give some other (illuminating) example of a value involving type T. (g) What is the name of the function defined by the programmer in the Haskell code? (h) Can a Haskell function have more than one type? yes / no. Explain, give an example. If a function can have more than one type, is there a best type? yes / no. Explain, give an example. (i) What is the type of the following function? (j) Apply the function to some value. What is the result? (k) Describe what the function does Consider the following Haskell data type and function, and answer the questions below: data T a = LF a|N(Ta) (Ta) (Ta) fg (LFx)=xfg (Nlcr) = g(fgl) (g(fgc) (fgr)) (a) What does it mean for a data type to be polymorphic?
