레이팅 미적용Barley the dog loves treats. At the end of the day he is either happy or
sad depending on the number and size of treats he receives throughout
the day. The treats come in three sizes: small, medium, and large. His
happiness score can be measured using the following formula:
$$ 1 \times S + 2 \times M + 3 \times L $$
where \(S\) is the number of small
treats, \(M\) is the number of medium
treats and \(L\) is the number of large
treats.
If Barley’s happiness score is \(10\) or greater then he is happy.
Otherwise, he is sad. Determine whether Barley is happy or sad at the
end of the day.
There are three lines of input. Each line contains a non-negative
integer less than \(10\). The first
line contains the number of small treats, \(S\), the second line contains the number of
medium treats, \(M\), and the third
line contains the number of large treats, \(L\), that Barley receives in a day.
If Barley’s happiness score is \(10\)
or greater, output happy. Otherwise, output
sad.
