For the matrix A=(0110)A = \begin{pmatrix} 0 & 1 \\ 1 & 0 \end{pmatrix}A=(0110), what is the transition matrix PPP that diagonalizes AAA?
(111−1)\begin{pmatrix} 1 & 1 \\ 1 & -1 \end{pmatrix}(111−1)
(1001)\begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}(1001)
(11−11)\begin{pmatrix} 1 & 1 \\ -1 & 1 \end{pmatrix}(1−111)
(0110)\begin{pmatrix} 0 & 1 \\ 1 & 0 \end{pmatrix}(0110)
