You have been stuck by what we call “Plagiarism Hammer”.
I usually dont talk on these matters but for your case, I think I should make things clear.
When I did, I was literally surprised. The rating distribution bar chart changed its form completely.
What do you mean by surprised? EVERYBODY caught by the MOSS judge under plagiarism is sent a mail regarding that. @admin asks for their justification so that false positives are eliminated. You got the chance to prove your innocence.
And by the way, I did have a look at the codes. Only the variable names are different. In fact, it feels as if someone copied your solution and pasted it with variable names changed. We cannot call this “co-incidence”.
However, in my case, it is still a mystery. I am penalised for an identical solution submitted by someone called @kapil_srivatsa, who lives in Chandigarh, over 1700 km away from where I live.
Admit it, this is pure nonsense. If this argument had any credit that “because of hundreds of km distance, they cant plagiarize my code” then we wouldn’t be needing MOSS. In the age of Internet (and ideone) everything is just a few clicks away.
How on earth could he possibly obtain my code, when I code completely offline, on Netbeans, in my personal laptop.
Your case seems to strongly suggest that your made your code public at ideone or any other online compiler. Or perhaps sharing it with friends on any messaging device.
His submission date is 10.11.17 while mine is on 04.11.17. Even if someone has to be penalised, then why me? He used some unfair means (I don't know what) to obtain my solution and submitted it after almost a week.
Both are penalized because making solutions public like this does an irreparable damage to fairness and spirit of contest.
With due respect, if the argument you sent her was “We are so far, how can he copy my code?” then I can see why you were not spared. If your codes are found identical, its your responsibility to get in touch and provide strong evidence. If you feel you are innocent, get in touch with them and explain your PoV. Dont do that if its otherwise, with years of expertise she can easily distinguish between honest guys and liars.
