Let's say we have a list of \code{Int} and want to add \code{2} to every element of the list.
|
||
|
|
\begin{haskellcode}
|
||
|
|
addTwo :: [Int] -> [Int]
|
||
|
|
addTwo ... ?
|
||
|
|
\end{haskellcode}
|
||
|
|
\pause

\textbf{Exercise:} Find the answer! 5 minutes time, remember the \emph{cons} operator \code{(:)}, pattern matching on lists and ofc recursion! Start with the case of an empty list.
