题目描述
Palindromic characteristics of string s with length ∣s∣ is a sequence of ∣s∣ integers, where k -th number is the total number of non-empty substrings of s which are k -palindromes.
A string is 1 -palindrome if and only if it reads the same backward as forward.
A string is k -palindrome ( k>1 ) if and only if:
- Its left half equals to its right half.
- Its left and right halfs are non-empty ( k−1 )-palindromes.
The left half of string t is its prefix of length ⌊∣t∣/2⌋ , and right half — the suffix of the same length. ⌊∣t∣/2⌋ denotes the length of string t divided by 2 , rounded down.
Note that each substring is counted as many times as it appears in the string. For example, in the string "aaa" the substring "a" appears 3 times.
输入格式
The first line contains the string s ( 1<=∣s∣<=5000 ) consisting of lowercase English letters.
输出格式

说明/提示
In the first example 1-palindromes are substring «a», «b», «b», «a», «bb», «abba», the substring «bb» is 2-palindrome. There are no 3- and 4-palindromes here.
