### 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>
using namespace std;
long long max(long long a, long long b) { return (a > b) ? a : b; }
long long min(long long a, long long b) { return (a > b) ? b : a; }
int32_t main() {
  ios_base::sync_with_stdio(false);
  cin.tie(NULL);
  cout.tie(NULL);
  string s;
  cin >> s;
  vector<long long> pos(26, -1);
  unordered_map<long long, long long> ans;
  long long ds = 0;
  for (long long i = 0; i < s.length(); i++) {
    if (pos[s[i] - 'a'] == -1) ds++;
    pos[s[i] - 'a'] = i;
    vector<long long> p;
    for (long long j = 0; j < 26; j++) {
      if (pos[j] != -1) {
        p.push_back(pos[j]);
      }
    }
    sort(p.begin(), p.end(), greater<long long>());
    if (p.back() != -1) p.push_back(-1);
    long long cnt = 1;
    for (long long j = 0; j < p.size() - 1; j++) {
      ans[cnt++] += p[j] - p[j + 1];
    }
  }
  cout << ds << endl;
  for (long long i = 1; i <= ds; i++) {
    cout << ans[i] << '\n';
  }
  return 0;
