Today while hacking(Codeforces Round #555: Div 3) I came across the following solutions by [user:4ul_sharma,2019-04-26] and [user:utkarshv3,2019-04-26] who are from the same institute.↵

↵
Problem B: Was there an actual need of sieve in [submission:53330133] by [user:4ul_sharma,2019-04-26] ? **'s1[s[i] — 48]'** and **val[s[i] — '0']** is the only difference in both solutions. [submission:53329059] is by [user:utkarshv3,2019-04-26].↵
↵
Problem C1: Similiar solution once again. [submission:53339717] is by [user:4ul_sharma,2019-04-26] and has been hacked. [submission:53337439] is by [user:utkarshv3,2019-04-26] (Expecting it to get hacked too) and you can observe the same pattern except change of variables and printing 'L' corresponding to 1 and 'R' corresponding to 0 in [user:4ul_sharma,2019-04-26]'s solution.↵
↵
Problem C2: [submission:53354481] is by [user:4ul_sharma,2019-04-26], [submission:53356166] is by [user:utkarshv3,2019-04-26]. Exactly similiar code, just change of variables. Again playing with 1 and 0 to print 'L' and 'R'.↵
↵
Problem D: [submission:53364711] is by [user:4ul_sharma,2019-04-26], [submission:53364674] is by [user:utkarshv3,2019-04-26]. Again a similiar code but change of variables.↵
↵
Problem E: [submission:53342437] is by [user:4ul_sharma,2019-04-26], [submission:53343985] is by [user:utkarshv3,2019-04-26]. And once again a similiar code with a few change of variables.↵
↵
The culprits involved are from the same college/organisation(JIIT Noida) : [user:4ul_sharma,2019-04-26] and [user:utkarshv3,2019-04-26].↵
↵
And you can notice the time of their submissions.↵

In such cases of cheating, what should be done? This is happening over and over again on this platform.↵
[user:MikeMirzayanov,2019-04-26] and [user:Vovuh,2019-04-26] please look into it.↵
