How to check two maps are equal in Golang 1.20
0In this video we are going to generate source code for the GoLang Program, How to check two maps are equal using chatGPT.
After generating we will verify and run the generated code.
IMPORTANT NOTE on SOURCE CODE: only source code that are acceptable by the youtube description box will be displayed.

package main
import "fmt"
func mapsEqual(m1, m2 map[string]int) bool {
if len(m1) != len(m2) {
return false
}
for k, v1 := range m1 {
if v2, ok := m2[k]; !ok || v1 != v2 {
return false
}
}
return true
}
func main() {
// Declare two maps of string keys and int values
ages1 := map[string]int{
"John": 30,
"Alice": 25,
"Bob": 35,
}
ages2 := map[string]int{
"John": 30,
"Alice": 25,
"Bob": 35,
}
// Check if the maps are equal
if mapsEqual(ages1, ages2) {
fmt.Println("The maps are equal")
} else {
fmt.Println("The maps are not equal")
}
}
Below is the explanation for the program:
In this program, we define a function mapsEqual that takes two maps of string keys and int values and returns a boolean indicating whether the two maps are equal.
The mapsEqual function first checks if the two maps have the same length. If they don't, it immediately returns false.
If the two maps have the same length, the function iterates over the keys of the first map using a for range loop.
For each key, it checks if the second map contains the same key and if the corresponding values are equal. If either of these conditions is not true, the function immediately returns false.
If the function has iterated over all the keys of the first map and hasn't returned false, it means that the two maps are equal, and the function returns true.
In the main function, we declare two maps of string keys and int values, ages1 and ages2, and initialize them with the same key-value pairs.
We then call the mapsEqual function with the two maps as arguments and print whether the maps are equal or not.
