Today, I checked some submissions of this account in the last Div.2: https://mirror.codeforces.com/profile/AzcNHc66 and found out some suspicious things.

In the first 3 problems (A-C) and the next 2 problems (D-E), his style code is somehow different a little bit. Check this:

• A, B, C: https://mirror.codeforces.com/contest/2020/submission/283557389, https://mirror.codeforces.com/contest/2020/submission/283560905, https://mirror.codeforces.com/contest/2020/submission/283569658.

• D, E: https://mirror.codeforces.com/contest/2020/submission/283564925, https://mirror.codeforces.com/contest/2020/submission/283584155.

Moreover:

• He solved D before than C. It's abnormal because how can he realized that problem D is easier, and he solved D in just 3 MINUTES??? Using DSU template in problem D is possible, but skip problem C and do D first is a very unusual move if you are doing speedforces.

• Style code in last 4 submissions has changed continuous.

So I can sure that there are two people doing this account in last contest. If it not like what i said, pls ignore this
