			class FindTheInverseOf2X2Matrix 
 { 

			    public static void main(String s[])
    {
        int input[][] = {{20, 45}, {2, 5}};
        double output[][] = getInverse(input);
        for (double[] array1d : output) {
        for (double element : array1d) {
        System.out.print(element + "   ");
        }
        System.out.println();
        }

    }
 
			

			

					    public static double[][] getInverse(int matrix[][]) {


					    }
