用java写大数,感觉就是BUG import java.math.*; import java.io.*; import java.util.*; public class Main{ public static void main(String[] args){ Scanner sc = new Scanner(System.in); BigDecimal f1, f2; int c = Integer.parseInt(sc.next()); int i = 1; while(sc.has…

Problem Description I have a very simple problem for you. Given two integers A and B, your job is to calculate the Sum of A + B. Input The first line of the input contains an integer T(1<=T<=20) which means the number of test cases. Then T lines fol…

http://acm.hdu.edu.cn/showproblem.php?pid=1002 输入的数都是正整数,比较好处理,注意进位. //非负大整数加法 # include <stdio.h> # include <string.h> # define MAX 1100 int main() { int t; char Num1[MAX], Num2[MAX], Num3[MAX];//Num3[] 用于保存结果 scanf("%d", &t); f…

#include <iostream>#include<stdio.h> using namespace std;int main(){ int T, count_T; char a[1001], b[1001], ans[1002]; cin >> T; for(count_T=1; count_T <= T; count_T++) { cin >> a >> b; int la=strlen(a)-1, lb=strlen(b)-1,…

1.大数加减法    思路分析:        1.将数据当做字符串输入(gets(s))        2.将字符型转换为整型,逆着存            char? int      i=0,j=len-1, int[i++]=char[j--]        3.从首位開始相加,              若sum>9,int[i]=sum%10,int[i+1]+=sum/10;        4.输入             1>推断int[len]是否为0.是的话跳过,不是的话输…

ACM中使用JAVA v2.1 严明超 (Blog:mingchaoyan.blogbus.com Email:mingchaoyan@gmail.com) 0.前 言 文前声明:本文只谈java用于acm,且不推荐大家把java作为自己的第一语言玩acm: 为防止大家过多的把本应学习算法的宝贵时间浪费在学习语言上,同时也为实现lcy一队一java的要求:我根据自己用java的经验,总结成文,希望可以抛砖引玉,帮助大家快速学会用java ac: Java对熟悉c/c++的选手来说应该是似曾相识的…
