A Trivial Problem
题意翻译
## 题目描述 圣塔先生要求世界上所有伟大的程序员解决一个小问题。他给了他们一个整数m,并要求正整数n的个数当n的阶乘恰好以m个0结束。您是能够解决这个问题的优秀程序员之一吗? ### 输入格式: 输入的唯一一行包含一个整数m (1<=m<=100000)代表阶乘中所需的尾随零的数量。 ### 输出格式 如果可以,输出一个整数k代表n的数量,接下来是k个n;如果不可以,输出0。题目描述
Mr. Santa asks all the great programmers of the world to solve a trivial problem. He gives them an integer $ m $ and asks for the number of positive integers $ n $ , such that the factorial of $ n $ ends with exactly $ m $ zeroes. Are you among those great programmers who can solve this problem?输入输出格式
输入格式
The only line of input contains an integer $ m $ ( $ 1<=m<=100000 $ ) — the required number of trailing zeroes in factorial.
输出格式
First print $ k $ — the number of values of $ n $ such that the factorial of $ n $ ends with $ m $ zeroes. Then print these $ k $ integers in increasing order.
