See trailing commas in Python for more. Code Style These terms are all about Python code style. Duck Typing A programming style characterized by focusing on the behavior of an object instead of the class (a.k.a. type) of that object. For example, a function that accepts a writable file...

Explanation: 5! = 120, one trailing zero. 1. 2. 3. Note: Your solution should be in logarithmic time complexity. 题目大意 递归 分析一下,就是看n!有多少个5组成。 计算包含的2和5组成的pair的个数就可以了。 因为5的个数比2少,所以2和5组成的pair的个数由5的个数决定。
