CF374D Inna and Sequence

Dima's spent much time thinking what present to give to Inna and gave her an empty sequence $ w $ . Now they want to fill sequence $ w $ with numbers zero and one. For that, they decided to play an amusing game. Before the game begins, Dima chooses $ m $ integers $ a_{1},a_{2},...,a_{m} $ $ (1

The first line of the input contains two integers $ n $ and $ m $ $ (1

In a single line print a sequence of numbers 0 and 1 — the elements of the sequence after all events happen. Print the elements of the sequence in the order from the beginning to the end of the sequence. If after all events the sequence ends up empty, print "Poor stack!".
