Tiling a Grid With DominoesTime Limit: 1000/500 MS (Java/Others) Memory Limit: 32768/32768 K (Java/Others)Total Submission(s): 939 Accepted Submission(s): 723 Problem Description We wish to tile a grid 4 units high and N units long with rectangles (dominoes) 2 units by one unit (in either orientation). For example, the figure shows the five different ways that a grid 4 units high and 2 units wide may be tiled. Write a program that takes as input the width, W, of the grid and outputs the number of different ways to tile a 4-by-W grid. Input The first line of input contains a single integer N, (1 ¡Ü N ¡Ü 1000) which is the number of datasets that follow. Each dataset contains a single decimal integer, the width, W, of the grid for this problem instance. Output For each problem instance, there is one line of output: The problem instance number as a decimal integer (start counting at one), a single space and the number of tilings of a 4-by-W grid. The values of W will be chosen so the count will fit in a 32-bit integer. Sample Input
