为什么错了呢???#include<iostream>
#include <math.h>
using namespace std;
int Add(int a[][100],int i,int k,int n,int N)
{
int yushu;
if(k>25&&n==0) return 0;
else
{
a[i][k]=a[i][k]*N+n;
yushu=a[i][k]/10;
a[i][k]%=10;
Add(a,i,k+1,yushu,N);
}
return 0;
}
int main()
{
int N,D,i,j,n=1,weishu=0;
int sum[100][100]={0};
for(i=0;i<25;i++)
{
cin>>N>>D;
if(N==0&&D==0) break;
if(D==0)
{
sum[i][1]=1;
continue;
}
else
sum[i][1]=1;
for(j=1;j<=D;j++)
{
Add(sum,i,1,0,N);
}
}
for(int k=0;k<i;k++)
{
weishu=0;
for(j=27;j>0;j--)
{
if(sum[k][j]!=0) weishu=1;
if(j==1&&sum[k][j]==0&&weishu==0) cout<<weishu+1;
if(weishu==0) continue;
else
cout<<sum[k][j];
}
cout<<endl;
}
return 0;
}
