Write a program which reads a word W and a text T, and prints the number of word W which appears in text T

T consists of string Ti separated by space characters and newlines. Count the number of Ti which equals to W. The word and text are case insensitive.

Constraints

* The length of W ≤ 10
* W consists of lower case letters
* The length of T in a line ≤ 1000

Input

In the first line, the word W is given. In the following lines, the text T is given separated by space characters and newlines.

"END_OF_TEXT" indicates the end of the text.

Output

Print the number of W in the text.

Example

Input

Output

3
#include<iostream>
#include<algorithm>

int main(){
  std::string word;
  std::cin >> word;

  int count = 0;
  std::string str;
  while(std::cin >> str){
    if(str == "END_OF_TEXT") break;
    std::transform(str.begin(), str.end(), str.begin(), ::tolower);
    if(str == word) count++;
  }

  std::cout << count << std::endl;

  
  return 0;
}
