 Note, in finding all routes across the river, we must never use more than one
 'digit log' consecutively.  This restriction is needed because the algorithm for
-adding 'digit logs' can mean we get digit logs that can be laid end to end.
+adding 'digit logs' can mean we get digit logs that can be laid end to end, and
+that case should always be ignored, since it is the same as having one larger
+digit log.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
