In his atcoder profile,he has mentioned that his birth year is 2010.
His Codeforces profile.
This is totally unbelievable for me, that how can someone achieve so much maturity in maths, problem-solving, analysis, deduction at so less age.
Is this some mistake that he has mentioned 2010 as his birth year?
If its not a mistake, then wont he be the youngest LGM on codeforces?
