Sample Output
5 1 4 2 3 |
#include<iostream> #include<algorithm> using namespace std; int main() { int n,i,flag,j; int a[10000]; while(cin>>n&&n) { for(i=0;i<n;i++) cin>>a[i]; sort(a,a+n);//默认升序 flag=0; for(i=0,j=n-1;i<=j;i++,j--) { if(flag==0) flag=1; else cout<<" "; if(i==j) cout<<a[i]; else cout<<a[j]<<" "<<a[i]; } cout<<endl; } return 0; }
