#include<iostream> #include<deque> using namespace std; int main() { int T; cin >> T; int m = T; while (T--) { int n; cin >> n; deque<int> q; q.push_back(n); int i = n - 1; while (i>0) { q.push_front(i); int x = q.back(); q.pop_back(); q.push_front(x); --i; } for (int j = 0; j<q.size()-1; ++j) cout << q[j] << " "; cout << q[q.size() - 1] << endl; } //system("pause"); return 0; } 不知道哪里错了？？？？？求大神指点
