CF24C Sequence of points

You are given the following points with integer coordinates on the plane: $ M_{0},A_{0},A_{1},...,A_{n-1} $ , where $ n $ is odd number. Now we define the following infinite sequence of points $ M_{i} $ : $ M_{i} $ is symmetric to $ M_{i-1} $ according  (for every natural number $ i $ ). Here point $ B $ is symmetric to $ A $ according $ M $ , if $ M $ is the center of the line segment $ AB $ . Given index $ j $ find the point $ M_{j} $ .

On the first line you will be given an integer $ n $ ( $ 1

On a single line output the coordinates of $ M_{j} $ , space separated.
