A topcoder topic, relatively simple

==============================================================

You and your friends is setting up a fantasy TopCoder league, where the Choose coders to is on your team and score points In the league if any one of your coders wins their or successfully challenges somebody, etc. To is fair, a system has been developed to choose the order in which picks is distributed. It works like This:first, lots is drawn to choose your position in the league. Then the player with the first position gets first pick, the second player gets second pick, all the the-the-the-until the last PL Ayer picks. Then the order reverses:the last player chooses again, then the next to last player, and so on, until you reach the first Player again. Then the cycle repeats:the first position chooses again, then the second, and so on.

For Example:say your were in the third position on a 6 player league. You would get the 3rd pick when you ' d wait until the 10th pick (the order would is 1,2,you,4,5,6,6,5,4,you), and then the 15th pick, and so on until there were no more coders to choose. If there were total picks and then you would get pick numbers 3,10,15.

Not wanting to miss your chance at a pick, your goal are to write a program this tells what do pick numbers you had in th E order that you have them. You'll receive three ints indicating your position in the league (1 being the first position) and the number of friends that is in the league with your, and the number of picks that is being divvied up among the league. You'll return an int[] that indicates the picks so you receive in ascending order.
