BEBRAS 2018 Grade 3-4 Round 2 Ext Question 15

The park has six letter-labelled trees. A letter is encoded by L and R turns from the entrance arrow, taking left or right at each junction.



For example A is LLL and R is LRR. Concatenating codes makes words: RLLLLRRLLL encodes SARA. How many L/R characters encode BEBRAS?
