Let A be an m × n matrix and Ban n × m matrix. It is given that determinant ($$I$$<sub>m</sub> + AB) = determinant ($$I$$<sub>n</sub> + BA), where $$I$$<sub>k</sub> is the k × k identity matrix. Using the above property, the determinant of the matrix given below is<br>\[\left[ {\begin{array}{*{20}{c}} 2&1&1&1 \\ 1&2&1&1 \\ 1&1&2&1 \\ 1&1&1&2 \end{array}} \right
