So judge Apra proposed going swimming at time $$$a$$$, and judge Mouf proposed going swimming at time $$$b$$$, so they started fighting and couldn't decide on a suitable time.

After much fighting, they decided to go swimming at the minimum time so they get to make it to the contest, but they are currently busy preparing the problems, so can you help them choose the minimum time?
