Problem

Ju-yeong was preparing for MatKor Cup at the Robot Convergence Hall of Korea University when Dong-woo invited him to eat sushi. Ju-yeong went to Howang Sushi. While they ate the assorted sushi, they had this exchange.

Dong-woo: "How many?"
Ju-yeong: "Huh?"
Dong-woo: "The rice grains. How many?"
Ju-yeong: "What's that supposed to mean?"
Dong-woo: "Three hundred twenty. A trained sushi master usually makes each piece with three hundred twenty grains of rice. Three hundred twenty is fine for a lunch meal, but on a day like today, or when it is served with alcohol, make it two hundred eighty, okay? So nobody gets too full."
Ju-yeong: "Where did you pick up this weird stuff?"
Dong-woo: "Do you know what The Youngest Son of a Chaebol is?"
Ju-yeong: "No."

Dong-woo was shocked that Ju-yeong did not know the drama that had shaken South Korea. Realizing how serious this was, Dong-woo gathered the MatKor members so that Ju-yeong would watch The Youngest Son of a Chaebol. The MatKor members thought that Ju-yeong would be more interested if he learned about the drama through an algorithm rather than simply watching the video. So they made a problem about the number of rice grains in a sushi piece. Then Dong-woo gave Ju-yeong the problem.

Dong-woo: "Today I will eat the sushi you make. You must make the sushi by following Chairman Jin-cheol's rule from The Youngest Son of a Chaebol. When I eat sushi with alcohol, or when I eat it at a time that is not lunch, each piece must have 280 grains of rice. When I eat it at lunch without alcohol, each piece must have 320 grains of rice. I have not decided yet when I will eat the sushi or whether I will drink with it. When I tell you the time and whether I have alcohol, you must find the number of rice grains each piece should have."

You are Ju-yeong. Solve Dong-woo's problem for him.

Input
