Find adj for `A=[[2 , 3 ] , [1 , 4]]`

Explanation

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

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