Given a square matrix, find the inverse of the given matrix. Determinant of a matrix is a prerequisite for this problem(go through the reference links once). The inverse of a matrix doesn't exist if its determinant is 0 that is when the matrix is Singular. So in case of singular matrix display '-1'.

Reference: Determinant of a matrix.

Reference: Adjoint and inverse of a matrix.

Input:

4

5 -2 2 7

1 0 0 3

-3 1 5 0

3 -1 -9 4

   where:

• First line represents the order of the square matrix.
• Second to fifth line represents the elements of the matrix.

Output:

-0.14 0.86 -0.68 -0.41

-0.64 2.36 -0.93 -0.66

0.05 0.05 -0.02 -0.11

0.05 0.05 0.23 0.14

Explanation: Output displays the inverse of the matrix.
