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.

Constraints

1 \leq |S| \leq 10

S consists of uppercase English letters.

Input

Input is given from Standard Input in the following format:

S

Output

If S starts with YAKI, print Yes; otherwise, print No.

Sample Input 1

YAKINIKU

Sample Output 1

Yes

YAKINIKU starts with YAKI.

Sample Input 2

TAKOYAKI

Sample Output 2
