Problem:
Finding a Word

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.

Solution in Python3 (judge verdict: Accepted)

import sys
word=input()
exam_text=[]
while True:
    text = input().split()
    if text[len(text)-1]=="END_OF_TEXT":
        break
    else:
        exam_text+=text
for i in range(len(exam_text)):
    exam_text[i] = exam_text[i].lower()

print(exam_text.count(word))
