一个出栈有多少种顺序的问题.一般都知道是Catalan数了. 问题是这个Catalan数非常大,故此须要使用高精度计算. 并且打表会速度快非常多.打表公式要熟记: Catalan数公式 Cn=C(2n,n) / (n+1); 递推公式 C(n ) = C(n-1)*(4*n-2) / (n+1) 高精度乘以一个整数和高精度除以一个整数的知识.这样还是使用整数数组比較好计算,假设使用string那么就不太好计算了,由于整数也可能是多位的. const int MAX_N = 101; short…

数字的反转: 就是将数字倒着存下来而已.(*^__^*) 嘻嘻…… 大致思路:将数字一位一位取出来,存在一个数组里面,然后再将其变成数字,输出. 详见代码. while (a) //将每位数字取出来,取完为止 { num1[i]=a%; //将每一个各位取出存在数组里面,实现了将数字反转 i++; //数组的变化 a/=; } 趁热打铁 例题:hdu 4554 叛逆的小明 题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4554 叛逆的小明 Time…

题目链接: http://acm.hdu.edu.cn/showproblem.php?pid=1002 题意: 数学题,A+B; 思路,这个数非常大,普通加法一定会超时,所以用大数加法.大数加法的基本思路是模拟我们做加法的时候的进位思想,从最低位开始模拟, 在我的代码里 v -- 进位, tmp -- 当前位2个数的和,k -- 答案数组的下标. 其中, tmp/10 可以得到要进的位数, 同理,tmp%10可以得到个位,就是答案数组对应的位 下面是AC代码: #include <iostre…

解题思路 两个⼤数可以⽤数组来逐位保存,然后在数组中逐位进⾏相加,再判断该位相加后是否需要进位.为了⽅便计算,可以把数字的低位放到数组的前面,高位放在后面. 样例输入 3 18 22 56 744 53234673473 7544645548767 样例输出 Case 1: 18 + 22 = 40 Case 2: 56 + 744 = 800 Case 3: 53234673473 + 7544645548767 = 7597880222240 代码实现 #include<stdio.h>…
