所有的正整数排在所有负数前面

One

<span style="font-size:18px;">#include<stdio.h>int num[1000]; int main() {int n,i;scanf("%d",&n);for(i=0;i<n;++i)scanf("%d",&num[i]);int j=n-1,flag=0;for(i=0;i<j;){while(num[i]>0) ++i;while(num[j]<0){--j;if(i>=j){flag=1;break;} } if(flag)break; int temp;temp=num[i];num[i]=num[j]; num[j]=temp; } for(i=0;i<n;++i)printf("%d ",num[i]);printf("\n");return 0; }</span>

Two
