filter two lambda arrays in go

main.go
package main

import (
    "fmt"
)

func main() {
    // Define the two arrays
    numbers1 := []int{1, 2, 3, 4, 5}
    numbers2 := []int{6, 7, 8, 9, 10}

    // Filter the arrays using anonymous functions
    filteredNumbers1 := filter(numbers1, func(n int) bool {
        return n%2 == 0
    })

    filteredNumbers2 := filter(numbers2, func(n int) bool {
        return n%3 == 0
    })

    // Print the filtered arrays
    fmt.Println(filteredNumbers1) // [2 4]
    fmt.Println(filteredNumbers2) // [6 9]
}

// The filter function takes an array and a lambda function and returns a new array
// with only the elements that passed the test in the lambda function
func filter(numbers []int, fn func(int) bool) []int {
    result := []int{}

    for _, n := range numbers {
        if fn(n) {
            result = append(result, n)
        }
    }

    return result
