Question

杭电acm求水仙花数,以下是我的代码不能通过，是presentation error

#include <stdio.h>
int main()
{
int n,m;
int i;
int flower(int);
while(scanf("%d%d",&n,&m)!=EOF)
{
int count=0;
for(i=n;i<=m;i++)
{
if(flower(i))
{
printf("%d ",i);
count++;
}
}
if(count!=0)
printf("\n");
else
printf("no\n");
}
return 0;
}
int flower(int i)
{
int a,b,c;
a=i%10;
b=((i%100)-a)/10;
c=(i-a-b*10)/100;
if(i==(a*a*a+b*b*b+c*c*c))
return 1;
else
return 0;
}

Answer 1

#include <stdio.h>
int main()
{
int n,m;
int i;
int flower(int);
while(scanf("%d%d",&n,&m)!=EOF)
{
int count=0;
int first=1;
for(i=n;i<=m;i++)
{
if(flower(i))
{
if(!first)
printf(" ");
first=0;
printf("%d",i);
count++;
}
}
if(count!=0)
printf("\n");
else
printf("no\n");
}
return 0;
}
int flower(int i)
{
int a,b,c;
a=i%10;
b=((i%100)-a)/10;
c=(i-a-b*10)/100;
if(i==(a*a*a+b*b*b+c*c*c))
return 1;
else
return 0;

}
每组数据最后一个数后没有空格，因为题目说水仙花数之间用空格隔开

Answer 2

#include <stdio.h>
int main()
{
int n,m;
int i;
int flower(int);
while(scanf("%d%d",&n,&m)!=EOF)
{
int count=0;
int flag=0;
for(i=n;i<=m;i++)
{
if(flower(i))
{
/*if(flag++) printf(" ");*/
printf("%d",i);//空格在两数中间
count++;
}
}
if(count!=0)
printf("\n");
else
printf("no\n");
}
return 0;
}
int flower(int i)
{
int a,b,c;
a=i%10;
b=((i%100)-a)/10;
c=(i-a-b*10)/100;
if(i==(a*a*a+b*b*b+c*c*c))
return 1;
else
return 0;
}
