Barley 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:

$\displaystyle 1 \times S + 2 \times M + 3 \times L$ $1 \times S + 2 \times M + 3 \times L$

where $S$ $S$ is the number of small treats, $M$ $M$ is the number of medium treats and $L$ $L$ is the number of large treats.

If Barley's happiness score is $10$ $10$ or greater then he is happy. Otherwise, he is sad. Determine whether Barley is happy or sad at the end of the day.

Input Specification

There are three lines of input. Each line contains a non-negative integer less than $10$ $10$ . The first line contains the number of small treats, $S$ $S$ , the second line contains the number of medium treats, $M$ $M$ , and the third line contains the number of large treats, $L$ $L$ , that Barley receives in a day.

Output Specification

If Barley's happiness score is $10$ $10$ or greater, output happy. Otherwise, output sad.

Most people passed first try, look at the stats graph.

Hint's for anyone coming across this comment:

Look closely at the formula, what can you do with this knowledge?

2nd, if you already know how to make variable have an inputed value, then all you need is 1 more step!(Hint: something to do with ifs and else ifs. Also something to do with the formula.)

And last, but not least, REMEMBER SPELLING! Spelling counts in these cases, test cases to be exact.

Hope you find these hints helpful! Upvote if yes!

CAPITALIZATION COUNTS ON THIS QUESTION! Don't make the same mistake I did and capitalize the first letters of the output...

Why does this problem have a 512 MB memory limit?

The memory limit reflects the limit from the CCC, but the time limit is smaller because the DMOJ judge is faster.
