C30 - Doing the computations by R, find the determinant of the matrix A.
\[ A = \left(\begin{array}{cc} 2 & 1 & 1 & 0 & 1\\ 2 & 1 & 2 & −1 & 1\\ 0 & 0 & 1 & 2 & 0\\ 1 & 0 & 3 & 1 & 1\\ 2 & 1 & 1 & 2 & 1 \end{array}\right) \]
A <- matrix(c(2, 1, 1, 0, 1, 2, 1, 2, -1, 1, 0, 0, 1, 2, 0, 1, 0, 3, 1, 1, 2, 1, 1, 2, 1), nrow = 5, ncol = 5, byrow = T)
det(A)## [1] 0
