 # Series
 
 Given a string of digits, output all the contiguous substrings of length `n` in
-that string.
+that string in the order that they appear.
 
 For example, the string "49142" has the following 3-digit series:
 
-- 491
-- 914
-- 142
+- "491"
+- "914"
+- "142"
 
 And the following 4-digit series:
 
-- 4914
-- 9142
+- "4914"
+- "9142"
 
 And if you ask for a 6-digit series from a 5-digit string, you deserve
 whatever you get.
 
 Note that these series are only required to occupy *adjacent positions*
