对于m是干什么的，实在是不明觉厉。

#include <cstdio>#include <cstdlib>#include <algorithm>using namespace std;typedef pair<int, int> pii;pii a[1000005];int main(){     int n, m; scanf("%d%d", &n, &m);        for (int i = 0; i <= n; i++)        scanf("%d", &a[i].first), a[i].second = i;            sort(a, a + n + 1);        for (int i = 1, t = a[0].second; i <= n; i++)        printf("%d ", a[t].first), t = a[t].second;        return 0;}
