下面是我为解决这个问题而编写的代码: '''
Returnsa dict with the prime factorization of the integer n, where the keys of the dict are the prime numbersand the values are the powers in the factorization
(setf (cdr (last content)) content))
"Returns a circular list containinga factorization (let ((circumference (apply #'* lstoptional (wheel (ring 4 2)))
"Returns primes up to n c
输出应将这些因素集合到单个字符串中,以便像prime_factorization(60)这样的调用的结果将字符串“60 = 2 x 2 x 3 x 5”打印到屏幕上。以下是我到目前为止所掌握的内容。""""Output is its prime factorization, computed as follows:
