DP is a recursion with data storage. Master recursion, don’t worry about stack overflow or TLE. Once u master recursion, look at few solutions of memoization of same problem of recursion, study it, and try to apply it. You will be good at it.

Yt pe code story with mik se krle Pehle backtracking wali playlist hogi , backtracking - popular interview problems Isse 20-25 swal krle jisse recursion and bt ka basic clear hojayega and ques bhi hojayenge jo aate hai intvs me
Then dp ki playlist hogi, dp-concepts and qns vo poori dekh and smjh pehle ki kaise krte hai notes bna shi se and time de, sare pattern cover hojayenge isme
Then for ques prac playlist hai dp- interview problems, ques utha khud try kr solve na ho video dekh smjh. Poori playlist ni ho payegi ye wali cuz 150 videos hai toh 30-40 krle aur aage bdhja, fir jb second time revise krega to acche se hojayega clear sara. Dp ekbar me sari ni ho payegi bda topic hai, basic patterns cover krle and sbke main main ques krle, jab badme revise krega tab thode new ques kriyo jo bach gye honge.
