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`.
print("YNeos"[not input()[:4] == "Yaki"::2])
s = input()
n = len(s)
if n<4:
  print("No")
elif s[:4] == "YAKI":
  print("Yes")
else:
  print("No")
