Revision en1, by whitepalace, 2024-02-06 21:37:01

There are many similiar codes in Problem E of Round 923(Div 3) which cause unfair to genuine coders.

Here is the plagiarized code:

include <bits/stdc++.h>

using namespace std;

ifdef LOCAL

include "algo/debug.h"

else

define debug(...) 42

endif

int main() { ios::sync_with_stdio(false); cin.tie(0); int tt = 1;; cin >> tt;; while (tt--) { int n, k; cin >> n >> k; vector v(n); vector a(k); a[0] = n; a[1] = 1; for (int i = 0; i < k; i++) { int sign = (i % 2 == 0 ? -1 : 1), move = 0, mn = n + 1, mx = 0; for (int j = i; j < n; j += k) { v[j] = a[i] + sign * move++; mx = max(mx, v[j]); mn = min(mn, v[j]); } if (sign == -1) { if (i + 2 < k) { a[i + 2] = mn — 1; } } else { if (i + 2 < k) { a[i + 2] = mx + 1; } } } for (int &it : v) { cout << it << ' '; } cout << '\n'; } return 0; }
