HDoj Integer Inquiry(大数)

真心要哭了。。这几天在搞大数 高精度计算 昨晚在机房敲 很快敲完了 就是过不了啊过不了 劳资都想骂脏话啊 NMB 一开始不输出前面的0啊 过不了 看discuss 百度 找了个AC的代码 找了几组测试数据 那个代码输出前面的0啊 我的妈 今天有找了个代码 不输出0啊 我的天。。。真心要被逼疯了 幸好还是AC了。。。算是有进步吧 之前的心态肯定坚持不下来啊

Integer Inquiry Time Limit: 2000/1000 MS (Java/Others) Memory Limit: 65536/32768 K (Java/Others) Total Submission(s): 11714 Accepted Submission(s): 2942 Problem Description One of the first users of BIT's new supercomputer was Chip Diller. He extended his exploration of powers of 3 to go from 0 to 333 and he explored taking various sums of those numbers. ``This supercomputer is great,'' remarked Chip. ``I only wish Timothy were here to see these results.'' (Chip moved to a new apartment, once one became available on the third floor of the Lemon Sky apartments on Third Street.) Input The input will consist of at most 100 lines of text, each of which contains a single VeryLongInteger. Each VeryLongInteger will be 100 or fewer characters in length, and will only contain digits (no VeryLongInteger will be negative). The final input line will contain a single zero on a line by itself. Output Your program should output the sum of the VeryLongIntegers given in the input. This problem contains multiple test cases! The first line of a multiple input is an integer N, then a blank line followed by N input blocks. Each input block is in the format indicated in the problem description. There is a blank line between input blocks. The output format consists of N output blocks. There is a blank line between output blocks.

题意很简单 就是输入一连串数字作为一个大的整数 遇到单个0结束输出

每个CASE输出之间 输出一个空行

#include <cstdlib>

using namespace std;

const int maxn=110;

char s[maxn];

int res[maxn];

int main()

{

int n;

cin>>n;

getchar();

while(n--)

{

memset(res,0,sizeof(res));

int m=0;

while(1)

{

gets(s);

if(strlen(s)==1&&s[0]=='0')

break;

int k=0;

for(int i=strlen(s)-1;i>=0;i--)

{

num[k++]=s[i]-'0';

//cout<<num[k-1]<<" ";

}

//cout<<endl;

m=max(m,k);

//cout<<"m1="<<m<<endl;

if(m>k)

{

for(int i=k;i<m;i++)

num[i]=0;

}

for(int i=0;i<m;i++)

{

res[i]+=num[i];

res[i+1]+=res[i]/10;

res[i]=res[i]%10;

}

//cout<<"res[m]="<<res[m]<<"res[m-1]"<<res[m-1]<<endl;

if(res[m]>0)

{

res[m]+=res[m-1]/10;

res[m-1]=res[m-1]%10;

m++;

}

}

//cout<<"m2="<<m<<endl;

// for(int i=m-1;i>=0;i--)

// cout<<res[i];

int flag=0;

int x=m-1;

for(;x>=0;x--)

{

if(res[x]>0)

flag=1;

if(flag)

cout<<res[x];

}

if(flag==0)

cout<<0;//如果输入的全是0 输出0

cout<<endl;

if(n)

cout<<endl;

}

return 0;

}

终究还是AC了 好开心。。。。
