直接输出ans1 188ptsWA on #4 #7 # 21
输出ans1 + 1 92pts 仅对 #4 #7 #21
说明主体代码没出问题，那么问题出在哪呢？
码

#include <bits/stdc++.h>
using namespace std;
int d[100005], ans1, ans2, a, w;
vector <int> f1;
vector <int> f2;
int main(){
	while (cin>>a){
		d[w++] = a;
	}
	f1.push_back(d[1]);
	f2.push_back(d[1]);
	for(int i = 2; i <= w ; i++){
        if(d[i] <= f1[ans1]){
            f1.push_back(d[i]);
			ans1++;
        }
		else {
            int p = upper_bound(f1.begin(), f1.end(), d[i], greater<int> ()) - f1.begin();
            f1[p] = d[i];
        } 
		if(d[i] > f2[ans2]){
			f2.push_back(d[i]);
			ans2++;
		}
		else {
            int q =  lower_bound(f2.begin(), f2.end(), d[i]) - f2.begin();
            f2[q] = d[i];
        }
        
	}
	printf("%d %d",ans1 + 1, ans2 + 1);//----注意这里！
	return 0;
