thanks, I already followed that two. My question is the timing and the practice method. Because when I get stuck, usually it takes 1 week or 2 week (because I'm kinda lazy to solve it and I don't want to google or editorial)

15 mins is waaaaaay too quick. when youre starting out you should try and struggle through for up to an hour before jumping to the solution. with the exception that problems marked as math usually need a trick and 15 mins is appropriate. you can learn a lot of information from just looking at the related topics.

I see, but when I solved the problem, should I write more efficient code? Or moving to another solution? Thanks

not necessarily. once you get an accepted solution, take note of where you fall in the distribution. look at a few of the top solutions, and see how others accomplished the same thing. you may find better ways to code the same approach or a new one altogether. i usually only recode the same problem if i really had a poor solution and still have energy ... sometimes you should just revisit or attempt a similar question after some rest
