### Prompt

In cpp, your task is to solve the following problem:

String diversity is the number of symbols that occur in the string at least once. Diversity of s will be denoted by d(s). For example , d("aaa")=1, d("abacaba")=3.

Given a string s, consisting of lowercase Latin letters. Consider all its substrings. Obviously, any substring diversity is a number from 1 to d(s). Find statistics about substrings diversity: for each k from 1 to d(s), find how many substrings of s has a diversity of exactly k.

Input

The input consists of a single line containing s. It contains only lowercase Latin letters, the length of s is from 1 to 3·105.

Output

Print to the first line the value d(s). Print sequence t1, t2, ..., td(s) to the following lines, where ti is the number of substrings of s having diversity of exactly i.

Examples

Input

abca


Output

3
4
3
3


Input

aabacaabbad


Output

4
14
19
28
5

Note

Consider the first example.

We denote by s(i, j) a substring of "abca" with the indices in the segment [i, j].

  * s(1, 1) =  "a", d("a") = 1
  * s(2, 2) =  "b", d("b") = 1
  * s(3, 3) =  "c", d("c") = 1
  * s(4, 4) =  "a", d("a") = 1
  * s(1, 2) =  "ab", d("ab") = 2
  * s(2, 3) =  "bc", d("bc") = 2
  * s(3, 4) =  "ca", d("ca") = 2
  * s(1, 3) =  "abc", d("abc") = 3
  * s(2, 4) =  "bca", d("bca") = 3
  * s(1, 4) =  "abca", d("abca") = 3



Total number of substring with diversity 1 is 4, with diversity 2 equals 3, 3 diversity is 3.

### Response

```cpp
#include <bits/stdc++.h>
const int MAX_N = 300050;
char s[MAX_N];
int pos[MAX_N];
int sa[30];
long long ans[30];
int k = 0;
int main() {
  scanf("%s", s + 1);
  int len = strlen(s + 1);
  for (int i = 1; i <= len; ++i) {
    if (pos[s[i] - 'a' + 1] == 0) k++;
    pos[s[i] - 'a' + 1] = i;
    for (int i = 0; i <= 27; ++i) sa[i] = pos[i];
    std::sort(sa, sa + 28);
    for (int i = 26; i >= 26 - k + 1; i--) ans[26 - i + 1] += sa[i + 1] - sa[i];
  }
  printf("%d\n", k);
  for (int i = 1; i <= k; ++i) printf("%I64d\n", ans[i]);
}
