If `A=[[1,-2,4],[0,2,1],[-4,5,3]]` find adj `A`.

Explanation

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

### Step 1: Find the Cofactor Matrix
The cofactor \( C_{ij} \) of an element \( a_{ij} \) in the matrix is calculated using the formula:
\[ C_{ij} = (-1)^{i+j} M_{ij} \]
where \( M_{ij} \) is the determinant of the submatrix formed by deleting the \( i \)-th row and \( j \)-th column.
