What is codeforces plagiarism checker doing these days?? See this two account and their submissions : code_ned and namanjain0501 Their submission in Codeforces Round 580 (Div. 2) (last Div2 contest):

Div2 C: code_ned submission: 59015997
namanjain0501 submission: 59021188

Div2 B: code_ned submission: 59024561
namanjain0501 submission: 59017320

In most of their submissions their code was similar with only change of few variables int it. Not only in this contest, their codes were similar to unacceptable extent in previous contests also!!
I want the Codeforces community and MikeMirzayanov to look into this !!
