A =int(input())
B = int(input())
C = int(input())
 
count5 = 0
count7 = 0
 
if A == 5:
    count5 = count5 + 1
if A == 7:
    count7 = count7 + 1
if B == 5:
    count5 = count5 + 1
if B == 7:
    count7 = count7 + 1
if C == 5:
    count5 = count5 + 1
if C == 7:
    count7 = count7 + 1
    
if count5 == 2 and count7 == 1:
