Counting the number of tilings of different sized boards with dominoes (i.e. 2 by 1 rectangles) can be a pretty difficult task. However, here you must only determine the number of ways to tile boards of height 3 and some width.

The input will contain 5 lines, each containing an integer 0 \le N \le 30, the width of the board you want to tile with dominoes.

The output will contain 5 lines, where each line represents the number of ways to tile a 3 \times N board with dominoes modulo 1\,000\,000 (i.e. The output is the remainder you get when you divide the number of ways to tile a 3 \times N board with dominoes by 1\,000\,000).
