( 586 ) E Triangles PROGRAMMING combinatorics dp 2600

B"Last summer Peter was at his granny's in the country, when a wolf attacked sheep in the nearby forest. Now he fears to walk through the forest, to walk round the forest, even to get out of the house. He explains this not by the fear of the wolf, but by a strange, in his opinion, pattern of the forest that has n levels, where n is an even number. In the local council you were given an area map, where the granny's house is marked by point H, parts of dense forest are marked grey (see the picture to understand better). After a long time at home Peter decided to yield to his granny's persuasions and step out for a breath of fresh air. Being prudent, Peter plans the route beforehand. The route, that Peter considers the most suitable, has the following characteristics: You should find the amount of such suitable oriented routes modulo 1000000009. The example of the area map for n xe2 x80 x89= xe2 x80 x8912 is given in the picture. Since the map has a regular structure, you can construct it for other n by analogy using the example. The input data contain the only even integer n (2 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89106). Output the only number -- the amount of Peter's routes modulo 1000000009."...
