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

  for(i=0; i<T.size(); i++)if(isupper(T[i]))T[i]=tolower(T[i]);
  if(W==T)match++;

  }
