Game cards#9081
Three boys (Peter, Ivan and Anatoly) were sharing playing cards. First, Peter gave Ivan and Anatoly as many cards as they had. Then Ivan gave Anatoly and Peter as much as they had. And finally, Anatoly gave Peter and Ivan as much as each of them had at that time. In the end, everyone got the same. How many cards did each of them have first?
The program enters one natural number from the keyboard: - the total number of cards (does not exceed ).
In a single line, write three integers separated by a space - the number of cards that Peter, Ivan and Anatoly had at first. If for the given value the problem has no solution, output one number -1.
