How do you plan to implement morphing of an apple tree object into an apple? What approaches do you see?

The implementation of morphing an apple tree object into an apple in Go can be viewed as transforming one data structure into another. Approaches:

1. Manual field mapping — write a function that takes an apple tree structure and returns an apple structure, copying and transforming the necessary fields.

2. Using mapping libraries — for example, automapper or similar, which simplify data copying between structures.

3. Interfaces and polymorphism — define an interface that both structures implement, and use methods for transformation.

Example of manual mapping:

package main

import "fmt"

type AppleTree struct {
    Height int
    Age    int
    Fruit  string
}

type Apple struct {
    Variety string
    Weight  float64
}

func MorphTreeToApple(tree AppleTree) Apple {
    // Example transformation: take the apple variety from the tree and set weight
    return Apple{
        Variety: tree.Fruit,
        Weight:  150.0, // grams
    }
}

func main() {
    tree := AppleTree{Height: 300, Age: 5, Fruit: "Golden Delicious"}
    apple := MorphTreeToApple(tree)
    fmt.Printf("Obtained apple: %+v\n", apple)
}
