Problem:
Finding a Word

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.

Sample Input

#include <ctype.h>
        
int main(void){
  char word[12],t_i[1010];
  int i,count=0;
        
  scanf("%s",word);
  for(i=0;i<strlen(word);i++)  word[i]=tolower(word[i]);
  while(1){
    scanf("%s",t_i);
    if(strcmp(t_i,"END_OF_FILE")==0)  break;
    for(i=0;i<strlen(t_i);i++)  t_i[i]=tolower(t_i[i]);
    if(strcmp(t_i,word)==0)  count++;
  }
        
  printf("%d\n",count);
        
  return 0;
