find the adjoint of the matrix `A=[(1,2,3),(0,5,0),(2,4,3)]`

Explanation

To find the adjoint of the matrix \( A = \begin{pmatrix} 1 & 2 & 3 \\ 0 & 5 & 0 \\ 2 & 4 & 3 \end{pmatrix} \), we will follow these steps:

### Step 1: Find the Cofactor Matrix

The cofactor matrix \( C \) is obtained by calculating the cofactor of each element of matrix \( A \).

#### Cofactor Calculation:
1. **Cofactor \( C_{11} \)**:
