Hi everyone!!!

I have been trying to find out some good tutorials on DP with Bitmasks. I managed to find this one and another one . But I found none of them explaining all the concepts related to the topic. I could not solve even a single question on DP with Bitmasks after reading them. Can somebody provide me some good resources where I can get some good code snippets with proper explanation as to how the code uses Bitmasks and how it is working for a problem.

Thanks!!!
