<?php

$array_data=array();
$end_word="END_OF_TEXT";

while(1){

	$x=trim(fgets(STDIN));

	// end_word?????¨?????????
	if($x==$end_word){

		break;
	}

	$array_data[]=$x;
}


// print_r($array_data);

$W=$array_data[0];

$cnt=0;
for($i=1;$i<count($array_data);$i++){

	WordCheck($array_data[$i],$W,$cnt);

}

printf("%d",$cnt);

function WordCheck($T,$W,&$cnt){

	// ??????????????§????§£?????????????????????
	foreach(explode(" ",$T) as $val){

		if(strtolower($val)==$W){

			$cnt+=1;
