**Problem Statement:**

Find the matrix \( P \) that diagonalizes the matrix 

\[ A = \begin{bmatrix} 1 & 0 & 0 \\ 0 & 1 & 1 \\ 0 & 1 & 1 \end{bmatrix} \]

and find the corresponding diagonal matrix. *(You can use a computer while finding eigenvalues and eigenvectors only!)*

**Explanation:**

The given task involves finding the matrix \( P \) that can diagonalize matrix \( A \), along with finding the corresponding diagonal matrix. Diagonalization is the process of finding a diagonal matrix \( D \) such that \( P^{-1}AP = D \), where \( P \) is the matrix comprised of the eigenvectors of \( A \), and \( D \) is a diagonal matrix with the eigenvalues of \( A \) on its diagonal.

To solve this problem, one needs to:
1. Find the eigenvalues of matrix \( A \).
2. Determine the eigenvectors for each eigenvalue.
3. Construct matrix \( P \) using these eigenvectors as columns.
4. Calculate the diagonal matrix \( D \) using the eigenvalues.

The matrix \( A \) given is a 3x3 matrix with the elements shown.
