Let P be a 3×3 real matrix having eigenvalues \(\lambda_1\) = 0, \(\lambda_2\) = 1 and \(\lambda_3\) = −1. Further, \(v_1=\begin{pmatrix} 1 \\ 0 \\ 0 \end{pmatrix}\), \(v_2=\begin{pmatrix} 1 \\ 1 \\ 0 \end{pmatrix}\) and \(v_3=\begin{pmatrix} 1 \\ 0 \\ 1 \end{pmatrix}\) are eigenvectors of the matrix P corresponding to the eigenvalues \(\lambda_1\), \(\lambda_2\) and \(\lambda_3\), respectively. Then the entry in the first row and the third column of P is
