matrix with file

Develop a program to find inverse of a square matrix. Program should accept the input matrix via a file. The name of the file should be accepted as an input from console. The file format from which to read the elements of the matrix is described below. A valid input consists of only numbers. In case of a bad input, program should output appropriate message as mentioned in output specification below.
Input Format:

Line 1

Absolute path of the first input file
Note:

Input in file column in table below is provided to help you visualize how the input file will look like. Your program should only accept name of the file as input.

Output

Print Inverse of the input matrix rounded up to 3 digits after decimal point, on console in the format shown in table below
