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.
