在 Go 语言中， map是一种强大、巧妙、通用的数据结构。 Golang Maps 是一组无序的键值对的集合。它被广泛使用，因为它提供了可以在键的帮助下检索、更新或删除的快速查找和值。
在 Go 语言中，您可以使用反射包提供的DeepEqual()函数将两个地图相互比较。如果两个地图都满足以下条件，则此函数返回 true：
- 两个映射都是 nil 或非 nil。
- 两个地图的长度相同。
- 两个映射是同一个映射对象，或者它们对应的键映射到非常相等的值。
否则，此函数返回 false。
句法：
reflect.DeepEqual(a, b)
这里， a 和 b 是映射，该函数检查 a 和 b 是否深度相等，然后返回布尔类型结果。
例子：
Go
// Go program to illustrate
// how to compare two maps
package main
import (
"fmt"
"reflect"
)
func main() {
map_1 := map[int]string{
200: "Anita",
201: "Neha",
203: "Suman",
204: "Robin",
205: "Rohit",
}
map_2 := map[int]string{
200: "Anita",
201: "Neha",
203: "Suman",
204: "Robin",
205: "Rohit",
206: "Sumit",
}
map_3 := map[int]string{
200: "Anita",
201: "Neha",
203: "Suman",
204: "Robin",
205: "Rohit",
}
map_4 := map[string]int{
"Anita": 200,
"Neha": 201,
"Suman": 203,
"Robin": 204,
"Rohit": 205,
}
// Comparing maps
// Using DeepEqual() function
res1 := reflect.DeepEqual(map_1, map_2)
res2 := reflect.DeepEqual(map_1, map_3)
res3 := reflect.DeepEqual(map_1, map_4)
res4 := reflect.DeepEqual(map_2, map_3)
res5 := reflect.DeepEqual(map_3, map_4)
res6 := reflect.DeepEqual(map_4, map_4)
res7 := reflect.DeepEqual(map_2, map_4)
// Displaying result
fmt.Println("Is Map 1 is equal to Map 2: ", res1)
fmt.Println("Is Map 1 is equal to Map 3: ", res2)
fmt.Println("Is Map 1 is equal to Map 4: ", res3)
fmt.Println("Is Map 2 is equal to Map 3: ", res4)
fmt.Println("Is Map 3 is equal to Map 4: ", res5)
fmt.Println("Is Map 4 is equal to Map 4: ", res6)
fmt.Println("Is Map 2 is equal to Map 4: ", res7)
}输出：
Is Map 1 is equal to Map 2: false
Is Map 1 is equal to Map 3: true
Is Map 1 is equal to Map 4: false
Is Map 2 is equal to Map 3: false
Is Map 3 is equal to Map 4: false
Is Map 4 is equal to Map 4: true
Is Map 2 is equal to Map 4: false
