B'Anton and Dasha like to play different games during breaks on checkered paper. By the 11th grade they managed to play all the games of this type and asked Vova the programmer to come up with a new game. Vova suggested to them to play a game under the code name "dot" with the following rules: Help them to determine the winner. The first line of the input file contains 4 integers x, y, n, d ( xe2 x80 x89- xe2 x80 x89200 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89x, xe2 x80 x89y xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89200, xe2 x80 x891 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89d xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89200, xe2 x80 x891 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x8920) -- the initial coordinates of the dot, the distance d and the number of vectors. It is guaranteed that the initial dot is at the distance less than d from the origin of the coordinates. The following n lines each contain two non-negative numbers xi and yi (0 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89xi, xe2 x80 x89yi xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89200) -- the coordinates of the i-th vector. It is guaranteed that all the vectors are nonzero and different. You should print "Anton", if the winner is Anton in case of both players play the game optimally, and "Dasha" otherwise. In the first test, Anton goes to the vector (1;2), and Dasha loses. In the second test Dasha with her first move shifts the dot so that its coordinates are (2;3), and Anton loses, as he has the only possible move -- to reflect relatively to the line y xe2 x80 x89= xe2 x80 x89x. Dasha will respond to it with the same move and return the dot in position (2;3).'...
