can anyone pls share any sheet or practice problems link or anything (easy -> medium -> hard) so that I can solve loads and loads of problems from dynamic programming, it would really help me improve dynamic programming, thank you :)

you cannot do nesting of post-increment operator whereas pre-increment nesting does not cause any problem

conclusion : never do post increment nesting

eg :

int a = 10;

 cout<<(++(++a))<<"\n";// valid in c++

 cout<<((a++)++); // in-valid in c++
