Go language shallow copy and deep copy

• Deep copy ： Copy the data , Two variables have different addresses , After copying, the operation of the two variables does not affect each other
• Shallow copy ： Copy address , After the copy, the operation of the two variables affects each other , Modification of one variable will affect another variable

package main

import (
	"fmt"
)

func main() {
	var src []int
	src = []int{1, 2, 3}
	fmt.Println(" Initial value src : ", src)

	fmt.Println("---------------------")

	des1 := src
	des2 := make([]int, len(src))
	copy(des2, src)
	fmt.Println(" Shallow copy des1: ", des1)
	fmt.Println(" Deep copy des2: ", des2)

	fmt.Println("---------------------")

	src[1] = 0
	fmt.Println(" modify src : ", src)
	fmt.Println("des1: ", des1)
	fmt.Println("des2: ", des2)
