Find the determinant of a square matrices whach are specified in the file to be uploaded.File format:
File must be ASCII file.
File can contain multiple matrices. Each matrix is preceded by a keyword MATRIX (case insensitive), optionally followed by the alphanumeric id. If id is ommited, sequential number is assigned as an id by default.
Next line must contain a single integer specifying the dimension of the matrix.
Next, Each matrix is represented by a sequence of its rows, each row in a separate line.
Elements of the matrix in a single row are separated by a single comma (',') character. Comma can't be used inside the number's representation.
Each element of a matrix must be a number in a decimal form, either as an integer or a floating point number. Exponent notation (e or E) can't be used.
All whitespaces surrounding numbers are ignored, as are the empty lines.
