I cannot yet finish a whole contest when i have been programming since long ago.I turned just yet to problemsets in order to improve.Except the lack of skills or knowledge I also feel intimidated by some problems.I have read a competitive programming book but it did just teach me some basic stuff like dynamic programming orbacktrackng which i haven't yet used in any problemin this competitive world.I must get better if anyone got any advice or wants to co-code during sundays I am up for it!!
