Hello !! I am kinda new to the field of CP, and I am honestly doing pretty good in terms of solving problems, but when it comes to contests, I take long time some times, I joined math Olympiads many times and have international ranks in it, so the first step of problem solving (the algorithm) don't take time at all ( 10 minutes in the worst cases), but I hardly ever turn my solution to real code quickly, and my codes are usually full of bugs, What do you advise me to do? Which type of problems should I work on more?
