Cheated D from the infamous YT Channel

Cheated C from the same place
#include<bits/stdc++.h>
using namespace std;
int w[100010];
void solve() {
int n, a, b; cin >> n >> a >> b;
int c = __gcd(a, b);
for(int i = 1; i <= n; i++) {
cin >> w[i];
w[i] %= c;
}
sort(w + 1, w + 1 + n);
int ans = w[n] - w[1];
for(int i = 1; i < n; i++) {
ans = min(ans, w[i] + c - w[i + 1]);
}
cout << ans << '\n';
}
int main() {
int t; cin >> t;
while(t--) {
solve();
}
selmon__bhoi check his submissions (has cheated 5 times already)
AbhiKundu2002 Pro cheater, check his submissions, you will find nonsensical similarities.
(has cheated 3 times)
MikeMirzayanov Please ban these cheaters asap.
stop it... why you posting it right after contest. they hurt you or what. wait till hacker check ended.
they hurt you or what. what do you mean ?
Also what is the point of posting it after the hacking phase ?
LOL. The hacking phase is during the contest
C is quite simple to implement so you can't tell if it is cheated or not
wait their code looked just like mine (the idea and stuff) am i gonna get caught or what ToT
Codes of C of all participants almost identical today (inc. me). So it might be coincidence.
Cannot comment about D, (couldn't solve).
