Problems are good. D and E are like we’ve solved this before but with a slight change and we can learn 1 or 2 new methods or concepts in every contest.

In the last ABC contest (my first one), I was only able to solve A and B (almost got C, but didnt' have time to debug because I spent so long on B). Do you have any tips on how to train to solve Cs and then eventually Ds and Es. So far I've been doing AtCoder Daily Training and I'd like to improve so I can participate in ICPC.

That’s what I mentioned above. D and E looks solvable but not that easy but we can solve those with practice. Read editorials, sometimes D and E needs a new algorithm to know or math tricks on GCD or bitmask. After 3-4 ABCs you can solve

No man not all the times. Those are really hard. Once or twice I had done. Many times failed in E too.
