Cheating in round 722 div 2
By reportplag, history, 4 years ago, In English

The regular cheater of codeforces Kaustov_584 has started cheating again. In today's Div 2 D problem this is his submission 117243132

He has also submitted problem B in the last minute which I am pretty sure he cheated in that too!

stopcheatingmyself has cheated in problem D too!

See his submission 117244766. He has copy pasted the bigint library from here Arpa's Big int library blog

If we remove that big int snippet we can easily see that both of them cheated. I am pretty sure they are not the only ones.

Thus I request MikeMirzayanov sir to take strict actions against these cheaters

They are just spoling the platform.

Its very sad to see even people who are expert+ cheat in cf.Here is the guy https://codeforces.net/profile/ambarsariya . This guy cheated today in cf div 2 d question.

This is the leaked code:

include <bits/stdc++.h>

define ll long long

const ll mod=998244353; const ll MAXN=1e6+1; using namespace std; ll spf[MAXN]; ll dp[MAXN][2];

int main() { for(ll i=0;i<MAXN;i++){ spf[i]=2; } spf[1]=1; for(ll i=2;i<MAXN;i++) for(ll j=2*i;j<MAXN;j+=i) spf[j]++; for(ll i=0;i<MAXN;i++) dp[i][0]=0,dp[i][1]=0; dp[1][0]=1,dp[1][1]=1; for(ll i=2;i<MAXN;i++){ dp[i][0]=dp[i-1][1]+spf[i]; dp[i][1]=dp[i-1][1]+dp[i][0]; dp[i][0]%=mod; dp[i][1]%=mod;

}
ll n;
cin>>n;
cout<<dp[n][0];
return 0;

}

Match with his code . u will get to know.

Such cheaters fool around to escape plag by using vector instead of array and somehow increase their rating.

[user:hello_algorithm][user:akashramjyothi] just see their solution of recent one eveything is same if you remove particular set of code. Even I A they have same solution, this define their level

And here the NYPD of codeforces arrives!! Kindly stop making these nonsense blogs.. no one cares who cheated or who hasn't. Blogs are there for people to learn and share their learnings, not to share your shitty investigation.

      Yeah the same trend, I don't even know who the fuck is this guy..!! neither do I care, just tired of shit posted by all of you cheat busters..! If you really care about cheating or some other fuck!! use some other social media for your research and spare codeforces. The blogs have always been cool here, and please continue the trend!

          I am not that guy.. and like really I am dumb..! I created this account for blogging on codeforces...! You people are unable to reach expert/cm on your own and keep digging out cheaters in that time. I am not even Indian like you guys...! Is there any LGM in your country?? No, because you guys focus on these shits instead of practicing and making yourself improve! You Indians cheat and just keep on cheating and also populate this platform with your shitty expose him to expose her blogs...! Yeah there is freedom of speech but not for these shits.. so please for the last time stop these shits!
