Sessão: condicionais (IF, ELSE/ SE SENAO)

這個 Issue 沒有描述。

The issue has no body and only names a session about conditionals, so inspect the repository's existing exercise/session structure before changing anything. Because it is very old and already has assignees, first ask whether the work is still wanted and what deliverable would count as done.
