1.2.16 Determinant calculation
Condition: Calculate the determinant of the matrix by reducing it to triangular form: \[ C=\left(\begin{array}{lllll} 0 & 1 & 2 & 1 & 1 \\ 1 & 0 & 1 & 0 & 1 \\ 2 & 1 & 0 & 1 & 0 \\ 1 & 1 & 1 & 2 & 1 \\ 1 & 1 & 1 & 1 & 0 \end{array}\right) \]
Calculation of determinants - both simple and complex, both low orders and higher ones.
