#include<stdio.h> int?main() {???? int?a[3001],b[3001];???? int?i,j,m=0;???? int?k=1,n;???? for(i=1;i<=3000;i++)??????? a[i]=i;???? for(i=2;i<=3000;i++)???????? for(j=i+1;a[j]<=3000;j++) ????????????if(a[j]!=0&&a[i]!=0) if(a[j]%a[i]==0)???????????????? a[j]=0;???? for(i=2;i<=3000;i++)???????? { if(a[i]!=0) { b[k]=a[i]; k++;} } scanf("%d",n); printf("%d\n",b[n]); return?0; }為什么會出現(xiàn)runtime error？？
