Re:我的电脑上运行是对的,而提交后wrong answer.不知输入数组int a[100000]够不够大.若不够怎样设?In Reply To:我的电脑上运行是对的,而提交后wrong answer.不知输入数组int a[100000]够不够大.若不够怎样设? Posted by:wangfanking at 2005-09-02 10:16:32 #include<stdio.h>
char *ch=new char[30];
long int input()
{
long int i,sum=0;
scanf("%s",ch);
if(ch[0]=='0') return 0;
for(i=0;ch[i]!=0;i++)
sum+=ch[i]-'0';
return sum;
}
int main()
{
long int i,j,k;long int sum;
i=input();
while(i)
{
sum=0;
while(i>0){
while(i>0)
{
j=i%10;//printf("%ld\n",i);
i=i/10;
sum+=j;
}
if(sum>=10) {i=sum;sum=0;}
}
printf("%ld\n",sum);
i=input();
}
return 0;
}
看看我的,可以参考一下,写得不好不要见怪,数组30就可以了
