怎么模拟? 我每次把剩下的数构成一个新的数组,可以节省很多运算量!但是还是TLE!但是在我电脑上感觉不出来很慢呀!输入3000立即就出来结果了!(内有程序,牛人帮下忙!)

#include "stdio.h"
#include "memory.h"
int a[34000];
int n;
int main()
{
	int i,k,c,len,len1,p;
	while(1)
	{
		scanf("%d",&n);
		if(n==0) break;
		for(i=0;i<34000;i++)
			a[i]=i+2;
        c=0;  len1=34000;
	    while(1)
		{
			c++;
			if(c==n) break;
			k=0; p=a[0];i=0;
			while(k<len1)
			{
				if(k%p!=0) 
				{
					a[i++]=a[k];
				}
				k++;
			}
			len1=i;
		}
		printf("%d\n",a[0]);
	}
return 1;
}
