How can I box in the bottom two lambdas?

$$

\left[\begin{array}{ccc}

\begin{array}{cccc|}

\lambda & 1 & 0 & \\

& \lambda & 1 & 0\\

& & \lambda & 1\\

& & & \lambda\\\hline

\end{array}

& & \\

& \begin{array}{c|}

\lambda\\\hline

\end{array} & \\

& & \begin{array}{c|}

\lambda\\\hline

\end{array}

\end{array}\right]

$$

On my pdf, it doesn't do this.
