If you are a beginner then go with easy problems first, try to solve as much you can for getting confidence. If, you are not able to solve easy problems then spend some time on that try to think harder, even you can't solve the problem go for editorial read the approach, don't read the code and try to solve your own spend time and practice gives you high return for sure. If you think you can solve easy problems go for a medium one. Go with the same approach as you have done with easy problems…even giving more time…
