func main() {
    matrix := [][]int{

        {0, 4, 0, 3},
        {0, 8, 0, 1},
    }

    // Get the number of rows
    rows := len(matrix)

    // Get the number of columns
    columns := len(matrix[0])

    totalCells := rows * columns

    fmt.Printf("Matrix size: %d rows x %d columns\n", rows, columns)
    fmt.Printf("Total Cells: %d\n", totalCells)
