显示前N个自然数,除数只有 2、3 和 7。我写了类似的东西。我是 Lisp 的初学者。谢谢!
defvar x 1
(defun numbers(n)
if(mod x 2 )
(loop for x from 1 to n
do(print x)
)
)
print(numbers())

因为我刚好有时间,你可以看看这个。可能不是完美的解决方案,但对于初学者来说应该是一个很好的起点。查看信息选项卡中的书籍以了解语法等。
(defun divisible-by (n m)
"Returns T if N is evenly divisible by M."
(zerop (mod n m)))
(defun numbers (n)
"Print all number upto N which are divisible by 2, 3 and 7."
(loop
for i from 1 upto N
if (and (divisible-by i 2) (divisible-by i 3) (divisible-by i 7))
do (format t "~D~%" i)))
