 [Alphametics](https://en.wikipedia.org/wiki/Alphametics) is a puzzle where
 letters in words are replaced with numbers.
 
 For example `SEND + MORE = MONEY`:
 
-```
+```text
   S E N D
   M O R E +
 -----------
 M O N E Y
 ```
 
 Replacing these with valid numbers gives:
 
-```
+```text
   9 5 6 7
   1 0 8 5 +
 -----------
 1 0 6 5 2
 ```
