B8. a) Rewrite the procedure given below, after eliminating tail recursion, if any. Assume that t and p are integers; t> 0 and p >=0. fun win(t,p) if p=0 then 2 else t*win(t,p-1) b) Rewrite the procedure given below, after eliminating tail recursion, if any. Assume that n is an integer and n >= 0. fun real (n) = if n=0 then 0.0 else 1.0 + real (n-1)
