我严重怀疑这个题目测试点有问题
其他网址可以AC 这里就不行了？
代码如下
#include <bits/stdc++.h>
#define x first
#define y second
// #define int long long
#define double long double
using namespace std;
using ll = long long;
using ull = unsigned long long;
using i32 = int;
using i64 = long long;
using u32 = unsigned int;
using u64 = unsigned long long;
using u128 = __int128;
// using ldouble = long double;
using pii = pair<int, int>;
using pis = pair<int, string>;
const double eps = 1e-7;
const int N = 6e5 + 10, C = 30;
int n, q;
int a[N];
int f[N][C];
double sum[N][C];
double ans;
int getmax(int l, int r) {
int res = l;
}
void solve(int l, int r, int &x) {
if (l > r || ans < eps)
return ;
}
signed main() {
stdiossync_with_stdio(false);
std::cin.tie(nullptr);
}
