Hello    

Solution: 

class count_word:
    def count(self,word):
        diction = {}
        for i in word.split():
            diction[i] = word.count(i)
        return diction

def max_word(diction):
        for n,c in diction.items():
            if(c==max(diction.values())):
                return n

if __name__=='__main__':
    word = input()
    c = count_word()
    d = c.count(word)
    print(max_word(d))

        self.bookId = bookId
        self.bookName = bookName

class Library:
    def __init__(self,libId,address,bookList):
        self.libId = libId
        self.address = address
        self.bookList = bookList
    def count_book(self,char):
        count = 0
        for i in bookList:
            if(i.bookName[0] == char):
                count = count + 1
            return print(count)
    def remove_book(self,books):
        for j in bookList:
            if j.bookName not in books:
                print(j.bookName)
               


if __name__=='__main__':
    count = int(input())
    bookList = []
    for i in range(count):
        bookId  = input()
        bookName = input()
        bookList.append(Book(bookId,bookName))
    libId = input()
    address = input()
    lib = Library(libId,address,bookList)
    char = input()
    books = []
    cnt = int(input())
    for j in range(cnt):
        books.append(input())
    out1 = lib.count_book(char)
    lib.remove_book(books)
