Problem: Given a string s, process q queries, each having one of the following forms:

  * 1 i c — Change the i-th character in the string to c. 
  * 2 l r y — Consider the substring of s starting at position l and ending at position r. Output the number of times y occurs as a substring in it. 

Input

The first line of the input contains the string s (1 ≤ |s| ≤ 105) of lowercase English letters.

The second line contains an integer q (1 ≤ q ≤ 105) — the number of queries to process.

The next q lines describe the queries and may have one of the following forms:

  * 1 i c (1 ≤ i ≤ |s|) 
  * 2 l r y (1 ≤ l ≤ r ≤ |s|) 



c is a lowercase English letter and y is a non-empty string consisting of only lowercase English letters.

The sum of |y| over all queries of second type is at most 105.

It is guaranteed that there is at least one query of second type.

All strings are 1-indexed.

|s| is the length of the string s.

Output

For each query of type 2, output the required answer in a separate line.

Examples

Input

ababababa
3
2 1 7 aba
1 5 c
2 1 7 aba


Output

3
1


Input

abcdcbc
5
2 1 7 bc
1 4 b
2 4 7 bc
1 2 a
2 1 4 aa


Output

2
2
1

Note

Consider the first sample case. Initially, the string aba occurs 3 times in the range [1, 7]. Note that two occurrences may overlap. 

After the update, the string becomes ababcbaba and now aba occurs only once in the range [1, 7].

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
char s[100005], t[100005];
bitset<100005> p[27], ini, ans;
inline int read() {
  int x = 0;
  char c = getchar();
  while (c < '0' || c > '9') c = getchar();
  while (c >= '0' && c <= '9') x = x * 10 + c - '0', c = getchar();
  return x;
}
int main() {
  int n, q, i, j, opt, l, r, len;
  scanf("%s", s + 1);
  n = strlen(s + 1);
  for (i = 1; i <= n; i++) {
    p[s[i] - 'a'][i] = 1;
    ini[i] = 1;
  }

    opt = read();
    if (opt == 1) {

    }
    l = read();
    r = read();

    len = strlen(t + 1);
    if (r - l + 1 < len) {
      puts("0");
      continue;
    }
    ans = ini;
    int res = 0;
    for (i = 1; i <= len; i++) {
      ans &= (p[t[i] - 'a'] >> (i - 1));
    }
    r -= (len - 1);
    if (r - l + 1 <= 66) {
      for (j = l; j <= r; j++) res += ans[j];
      printf("%d\n", res);
      continue;
    }
    unsigned long *o = (unsigned long *)&ans;
    while (l & 31) res += ans[l++];
    while (r & 31) res += ans[r--];
    res += ans[r];
    l >>= 5;

    for (j = l; j < r; j++) {
