#include "art.h" #include <bits/stdc++.h> using namespace std; // // --- Sample implementation for the task art --- // // To compile this program with the sample grader, place: // art.h art_sample.cpp sample_grader.cpp // in a single folder, then open the terminal in this directory (right-click onto an empty spot in the directory, // left click on "Open in terminal") and enter e.g.: // g++ -std=c++17 art_sample.cpp sample_grader.cpp // in this folder. This will create a file a.out in the current directory which you can execute from the terminal // as ./a.out // See task statement or sample_grader.cpp for the input specification // template<typename T> using vec = vector<T>; template<class T, class S> inline bool chmax(T &a, const S &b) { return (a < b ? a = b, 1 : 0); } template<class T, class S> inline bool chmin(T &a, const S &b) { return (a > b ? a = b, 1 : 0); } void solve(int n) { vec<int> p(n); iota(p.begin(), p.end(), 1); sort(p.begin(), p.end(), [&](int a, int b) { vec<int> v(n); v[0] = a; v[1] = b; set<int> s; for (int i = 1; i <= n; i++) { if (i == a || i == b) continue; s.insert(i); } for (int i = 2; i < n; i++) { v[i] = *s.begin(); s.erase(s.begin()); } int p1 = publish(v); swap(v[0], v[1]); int p2 = publish(v); return p1 < p2; }); // for (int i = 0; i < n; i++) { // for (int j = 0; j < n - 1; j++) { // int val = publish(p); // swap(p[j], p[j + 1]); // int val2 = publish(p); // if (val2 > val) { // swap(p[j], p[j + 1]); // } // } // } answer(p); }
