Ambar Submission 117247731 Same submission 117243132
I know you guys are not ready to accept but its your choice .
Math his submissions of any last problem he solved with hello algorithm , you will get your answer .
It was the last update from my side .
You can follow virtual contest , nothing bad it that but keep in mind that dont get blown by fake ratings .

twoseven is a youtuber who do some virtual contests .
He also have a youtube channel and he is cheating continuously .
Today his solution D was also copied .
He has cheated in almost every contest and has been mentioned many times in CF blogs .
I have all the solutions which he have copied and from whom .
Just one request stop misguiding beginners by creating fake influence .
I have just written this to all those who follow him .
please down vote this blog ( so it will not be listed in recent blogs )as this is not the need of community .
Thank YOU .
I have send its proof to his followers , if any one is seeing mention in comments ( it will be ok if you do not do such ) .
The blog is just to warn you guys :-)








Shame on you twoseven!!!!! You have cheated too!
Never expected this from you!
You also submitted problem D in the last minute just like other cheaters!
youre the same person from the blog with different id lol
Post the proof here itself.
Are you jealous of his growing popularity? I also gave his virtual, he do the screencasts. None of the blog on him ended with result that he is a cheater,because he is not. You are just putting his image down in the community so that he can't grow.
Stop these NON EDUCATIONAL BLOGS and let us learn new concepts.
Its very sad to see even people who are expert+ cheat in cf.Here is the guy https://mirror.codeforces.com/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;
}
His code: ll modadd(ll a, ll b, ll m = MOD) { a = a % m; b = b % m; return (((a + b) % m) + m) % m; } ci(n); ll fac[n + 2]; forn(i, 0, n + 2) { fac[i] = 2; } fac[1] = 1; forn(i, 2, n + 2) { for(ll j = 2 * i; j < n + 2; j += i) { fac[j] ++; } } vector<vector> dp(n + 2, vector(2, 0)); dp[1][0] = 1; dp[1][1] = 1; forn(i, 2, n + 2) { dp[i][0] = modadd(dp[i — 1][1], fac[i]); dp[i][1] = modadd(dp[i — 1][1], dp[i][0]); } cout<<dp[n][0]<<Endl; return;
Match with his code . u will get to know. He used vector instead of array and the dp states is totally same.
Such cheaters fool around to escape plag by using vector instead of array and somehow increase their rating.
Cf take action against this guy . He tries his best to escape plag . And the supporters don't be blind . If u know basic coding u will get to know he totally cheated today's d question. Just match his code and leaked code.
I have myself observed this thing Youtubers like h1teshtr1path1 they just cheat and post solutions. This is the reason they are not specialist or expert from 1-2 years. Coz sometimes they get solutions they become specialist and sometimes they don't get so they become pupil again. My friend who usually cheats told me that he got DM from hitesh tripathi from fake telegram ID in a live contest with his exact template and ready to exchange with other problem.
Afterwards i tried checking and it matched from hitesh's solution! This happened just 2-3 contests back.
Shame on such people! Just unsusbcribe such people.
Guys don't be blind . Look at both solution and then judge whether he cheated or not. Just see both the solutions : https://mirror.codeforces.com/contest/1529/submission/117247731
https://mirror.codeforces.com/contest/1529/submission/117243132
Now see this guy ambarsariya's solution, he used vector instead of array to just avoid plag. Whole dp states and logic of code and structure is totally same.
