Let $A$ and $B$ be finite alphabets and let $\#$ be a symbol outside both $A$ and $B$. Let $f$ be a total function from $A^{*}$ to $B^{*}$. We say $f$ is computable if there exists a Turing machine $M$ which given an ... $L_{f}$ is recursive, but not conversely. If $f$ is computable then $L_{f}$ is recursively enumerable, but not conversely.
