Suppose you live in a computer world and you are a single boy, you want to be double. In the computer world being double is not so hard as our world, even you don’t need to propose. The only thing you have to do is to show your power. Initially your power is P. There are some girls in the computer world. Every girl has a beauty B and they are standing in increasing order according to their beauty. That means less beauty girl will be in the first position. Suppose there are four girls and their beauties are 4 3 2 1.  They are standing (1 2 3 4) in this order. To be double you must meet with some girl and have to show your power. If your power is greater than or equal to that girl’s beauty, then the girl will be impressed by you and fall in love with you. If a girl’s beauty is more than your power, then she will not like you and you have to go other girls. Remember that when you are showing your power, your power will not decrease, because you are only showing it, not using it. You can show your power to multiple girls.

Your goal is to impress girls as many as possible.
