This is a template problem.
Read into a string of n -Length lowercase English letters, order all non-null suffixes of the string from small to large in the dictionary order, and then sequentially output the position of the first character of the suffix in the original string. The position number is 1 to n.
In addition to further proving that you do have the ability to sort suffixes, please also output n−1 integers representing the length of the longest common prefix of the neighboring suffix after sorting.
Input format
A single line of n -length strings containing only lowercase English letters.
Output format
The first row n integers, and the I integer represents the position of the first character in the original string for the suffix of i .
Second linen−1 An integer, section i integers represent the length of the longest public prefix that is ranked i and the suffix ranked i+1 .
Sample One input
Ababa
Output
5 3 1 4 21 3 0 2
Explanation
After sorting the result is:
- a
- aba
- ababa
- ba
- baba
