Hi, community.

Currently, I have a job in the C++ industry, and I have personal projects related to computer graphics, but I want to complement this with programming problem resolution.

I want to know the best options to practice programming problems if possible related to mathematics, gameplay or computer graphics.

I know the following web pages:

Project Euler: More oriented to mathematics

TopCoder

CodinGame: Apparently, more oriented to gameplay

CodeAcademy: It looks like is oriented to LEARN to program.

HackerRank

CodeFights

Any recommendation? What do you suggest?

Thanks in advance!

I think I found the answer in Google.
