Description
A message string message must be split into parts. Each part must be formatted as "<part_text><b>" where <b> denotes the suffix "<index>/<count>", with <index> being the 1-based part number and <count> being the total number of parts. Each part (including the suffix) must not exceed limit characters.
Return the list of parts in order, or an empty list if it is impossible to split the message under the given limit.
Example 1:
Input: message = "this is really a very awesome message", limit = 9
Output: ["thi<1/14>","s i<2/14>","s r<3/14>","eal<4/14>","ly <5/14>","a v<6/14>","ery<7/14>"," aw<8/14>","eso<9/14>","me<10/14>"," m<11/14>","es<12/14>","sa<13/14>","ge<14/14>"]
Explanation:
The first 9 parts take 3 characters each from the beginning of message.
The next 5 parts take 2 characters each to finish splitting message.
In this example, each part, including the last, has length 9.
It can be shown it is not possible to split message into less than 14 parts.
Example 2:
Input: message = "short message", limit = 15
Output: ["short mess<1/2>","age<2/2>"]
Explanation:
Under the given constraints, the string can be split into two parts:
- The first part comprises of the first 10 characters, and has a length 15.
- The next part comprises of the last 3 characters, and has a length 8.
