Hi everyone, I'm newbie to informatic and Codeforces. I have just finished my C++ class and now I am learning about algorithm. My teacher told that I should practice, practice and practice problems on some online judge webs but I feel tired. I'm just learning informatic 2 months and have no idea about algorithm. I always want to be a good algorithm programmer but I couldn't choose a effective method to learning it. Can anyone help me some way, learning algorithm before practice or practice then find algorithm compatible or another method? I'll very greatful for the help.
