Welcome to the Erechim Winter School of the ICPC Brazilian Subregional Contest! We sincerely hope you learn a lot during these days so you can be very successful in the Programming contests yet to come, but above all we hope you enjoy the School, for when we have fun and enjoy ourselves studying and programming, the training stops being a burden and becomes a hobby. So, have fun!

The winter is a wonderful season, is it not? We all love wearing a poncho, joining a chimarrão circle, baking pinhões in a wooden burning stove… But not everyone likes the winter, especially in places where winter uses to be very cruel. In Westeros, for example, the people's humour is defined according to climate tendencies. Based on the temperatures of the last three days, the people can be sad or happy, being more likely to make war or to make love, respectively. And, let us be honest, it is precisely because of the scenes of love and war that we love Game of Thrones!


The input consists only of three integers, A, B e C (-100 ≤ A, B, C ≤ 100), which represent respectively the temperatures recorded in the 1st, in the 2nd and in the 3rd day.


Print a line containing a happy or a sad smiley, representing how is the humour of the people of Westeros according to the climate tendencies.
