Takahashi is competing in a sumo tournament. The tournament lasts for 15 days, during which he performs in one match per day. If he wins 8 or more matches, he can also participate in the next tournament.  The matches for the first k days have finished. You are given the results of Takahashi's matches as a string S consisting of `o` and `x`. If the i-th character in S is `o`, it means that Takahashi won the match on the i-th day; if that character is `x`, it means that Takahashi lost the match on the i-th day.  Print `YES` if there is a possibility that Takahashi can participate in the next tournament, and print `NO` if there is no such possibility.
S = input()
x = 15 - len(S)
y = 8 - S.count("o")
ans = "Yes" if x - y >= 0 else "No"
print(ans)
S = input()
k = len(S)
x = 15 - k
y = 8 - S.count("o")
ans = "YES" if x - y >= 0 else "NO"
print(ans)
