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

computer
Nurtures computer scientists and highly-skilled computer engineers
who will create and exploit "knowledge" for the new era.
Provides an outstanding computer environment.
END_OF_TEXT

Sample Output

Solution in Ruby (judge verdict: Wrong Answer)

MODE = "stdio"
require 'matrix'
line = Array.new

if(defined? MODE)
  line = STDIN.read.split("\n")
else
  tmp = 'computer
  Nurtures computer scientists and highly-skilled computer engineers
  who will create and exploit "knowledge" for the new era.
  Provides an outstanding computer environment.
  END_OF_TEXT'.split("\n")
  tmp.each{|s|
    line << s.strip
  }
end

w = line[0].downcase
s = ""
n=1
while true
  a = line[n]
  break if a=="END_OF_TEXT"
  s += a.downcase
  n += 1
end

puts s.split(" ").count(w)
