#table 是密碼表，獲取字母對應的數字，之後依照題目寫演算法，最後判斷並輸出

 

table={'A':10,'J':18,'S':26,'B':11,'K':19,'T':27,'C':12,'L':20,'U':28,'D':13,'M':21,'V':29,'E':14,'N':22,'W':32,'F':15,'O':35,'X':30,'G':16,'P':23,'Y':31,'H':17,'Q':24,'Z':33,'I':34,'R':25}

while True:

    try:

        n=input()

    except EOFError:

        break

    Alpha=str(table[n[0]])

    Alpha=int(Alpha[0])+int(Alpha[1])*9

    sum=0

    for i in range(1,9):

        sum+=int(n[i])*(9-i)

    sum+=int(n[9])+Alpha

    if sum%10==0:

        print('real')

    else:

        print('fake')
