I'll be very short and clear:

PROBLEM: I want to learn Bitmasks DP and I am having trouble learning it.

What I did: I read few tutorials on a few websites such as HackerEarth, Quora, etc. I have got a little clue of what it's all about, but I don't have the complete picture and I am not able to solve problems.

How you can help: If you can provide links to some good beginner questions (that has an explanation for the solution), that would be really helpfull.

Thank You!!
