array = list(map(int, input().split()))                                                        
  
sort_array = array.sort()
 
for i in range(len(array)):
    if i == 0 and array[i] == 5:
        continue
    elif  i==0 and not(array[i]) == 5:
        print("No")
        break
 
    if i==1 and array[i] == 5:
        continue
    elif  i==1 and not(array[i]) == 5:
        print("No")
        break
 
 
    if i==2 and array[i] == 7:
        print("Yes")
