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

    if(str=="END_OF_TEXT")break;
    std::transform(str.begin(),str.end(),str.begin(),tolower);
    if(str==W){
      count++;
    }
  }
  std::cout<<count<<std::endl;
