我和你一样是RE
#include <iostream> #include <vector> #include <algorithm> using namespace std; int main() { long long n, m; cin >> n >> m; vector<vector<int>> balls(n, vector<int>(m)); for (int i = 0; i < n; i++) { for (int j = 0; j < m; j++) { cin >> balls[i][j]; } } vector<pair<int, int>> moves; for (int color = 0; color < m; color++) { vector<pair<int, int>> count; for (int i = 0; i <= n; i++) { int cnt = 0; for (int j = 0; j < m; j++) { if (balls[i][j] == color) { cnt++; } } count.push_back({cnt, i}); } sort(count.begin(), count.end()); for (int i = 0; i < n; i++) { if (count[i].first == 0) break; long long from = count[i].second; long long to = count[n].second; moves.push_back({from + 1, to + 1}); balls[to][count[n].first - 1] = balls[from][count[i].first - 1]; balls[from][count[i].first - 1] = 0; } } cout << moves.size() << endl; for (auto move : moves) { cout << move.first << " " << move.second << endl; } return 0; }6啊
