我认为单是需要优化暴力这一部分就能让这题不是红

```cpp
signed main() {
int n, w, ans = 0;
n = read<int>(), w = read<int>();
if (w == 0) {
write(0);
return 0;
}
for (int i = 1; i <= n; i++) {
int x, b;
x = read<int>(), b = read<int>();
a[x] += b;
}
for (int i = 1; i <= w; i++) {
ans += a[i];
}
for (int i = w + 1; i <= n; i++) {
ans -= a[i - w];
ans += a[i];
if (ans > maxx) maxx = ans;
}
write(maxx);
return 0;
}
```
这不直接A了？
