很好奇为什么下载的测试点自己测试是对的，洛谷测试wa了呢？代码如下：

include<iostream>

include<iomanip>

include<math.h>

include<cstring>

include<string>

include<fstream>

include<sstream>

include<algorithm>

include<vector>

using namespace std;

bool compare( vector<int> x,vector<int> y) {

return x[1] < y[1];

} int main() {

int n, s, a, b;
int count = 0;
vector<vector<int> > xy ;
cin >> n >> s >> a >> b;
for (int i = 0;i < n;i++) {
    int xi, yi;
    cin >> xi >> yi;
    xy.push_back({ xi,yi });
}
sort(xy.begin(), xy.end(), compare);
for (int j = 0;j < n;j++) {
    if (s > 0) {
        if ((a + b) >= xy[j][0] && (s - xy[j][1] >= 0)) {
            count++;
            s -= xy[j][1];
        }
        else if (s - xy[j][1] < 0)
            break;
    }
}
cout << count;

}

include<iostream>
include<iomanip>
include<math.h>
include<cstring>
include<string>
include<fstream>
include<sstream>
include<algorithm>
include<vector>
using namespace std;
bool compare( vector<int> x,vector<int> y) {
return x[1] < y[1];
} int main() {
int n, s, a, b;
int count = 0;
vector<vector<int> > xy ;
cin >> n >> s >> a >> b;
for (int i = 0;i < n;i++) {
    int xi, yi;
    cin >> xi >> yi;
    xy.push_back({ xi,yi });
}
sort(xy.begin(), xy.end(), compare);
for (int j = 0;j < n;j++) {
    if (s > 0) {
        if ((a + b) >= xy[j][0] && (s - xy[j][1] >= 0)) {
            count++;
            s -= xy[j][1];
        }
        else if (s - xy[j][1] < 0)
            break;
    }
}
cout << count;
return 0;
}
