Condition We have a database of user passwords, which are hashed (using the hashPassword function), and we also know the set of characters that can be used in passwords (the variable alphabet). Our task is to implement the RecoverPassword function so that it recovers the password from the known hash and TestRecoverPassword completes successfully. Basic requirements: Solve as you wish package main import ( "crypto/md5" "fmt" ) var alphabet = []rune{'a', 'b', 'c', 'd', '1', '2', '3'} func RecoverPassword(h []byte) string { return "" } func hashPassword(in string) []byte { h := md5.Sum([]byte(in)) return h[:] } func main() { tests := []string{"a", "12", "abc333d"} ok := true for _, exp := range tests { h := hashPassword(exp) act := RecoverPassword(h) if act != exp { fmt.Printf("Error: expected %q, got %q\n", exp, act) ok = false } } if ok { fmt.Println("All tests passed successfully") } }
