Ringo is giving a present to Snuke.  Ringo has found out that Snuke loves _yakiniku_ (a Japanese term meaning grilled meat. _yaki_ : grilled, _niku_ : meat). He supposes that Snuke likes grilled things starting with `YAKI` in Japanese, and does not like other things.  You are given a string S representing the Japanese name of Ringo's present to Snuke. Determine whether S starts with `YAKI`.
s = str(input())
if s[0:3] == "YAKI":
    print("Yes")
else:
    print("No")
s = str(input())
if s[:4] == "YAKI":
    print("Yes")
else:
    print("No")
