这道大数乘法开始我是想套板子模拟的..然后就发现2/3的例子都wa了.(惊了).然后在思考后发现n2的板子的确过不了这么多的大数.(不看题的下场).所以,我在网上发现了分块求大数的方法.%%% 思路来自这位大佬的帖子>>http://blog.csdn.net/f_zyj/article/details/51187056<< 总的来说,就是把这个乘积分成8位数(自己定)一小块,然后考虑进位,最后倒着输出来就行. 代码如下: #include<iostream> #inc…

题目连接:http://acm.hdu.edu.cn/showproblem.php?pid=1042 题目大意:求n!, n 的上限是10000. 解题思路:高精度乘法 , 因为数据量比较大, 所以得用到缩进,但因为是乘法,缩进只能在10^5, 不然在乘的过程中就超过int型.然后数值位数大概在8000位以下. #include <iostream> #include <string.h> using namespace std; const int MAXN = 100000;…
