Modify the make-account procedure so that it creates password-protected accounts. That is, make-account should take a symbol as an additional argument, as in (define acc (make-account 100 'secret-password)) The resulting account object should process a request only if it is accompanied by the password with which the account was created, and should otherwise return a complaint: ((acc 'secret-password 'withdraw) 40) 60 ((acc 'some-other-password 'deposit) 50) "Incorrect password"（please use lisp）

下面是使用 Lisp 语言编写的修改后的 `make-account` 过程：

(define (make-account balance password)
  (define (withdraw amount)
    (if (>= balance amount)
        (begin (set! balance (- balance amount))
               balance)
        "Insufficient funds"))
  (define (deposit amount)
    (set! balance (+ balance amount))
    balance)
  (define (dispatch pw m)
    (if (eq? pw password)
        (cond ((eq? m 'withdraw) withdraw)
              ((eq? m 'deposit) deposit)
              (else (error "Unknown request -- MAKE-ACCOUNT"
                           m)))
        "Incorrect password"))
  dispatch)

这个过程接受两个参数：账户余额和密码。返回一个带有两个参数的过程，其中第一个参数是密码，第二个参数是操作类型（'withdraw 或 'deposit）。如果密码正确，过程将执行相应的操作。如果密码错误，过程将返回“Incorrect password”字符串。
