Hi All,

I havent been very active on LC but would want to start practicing seriously. I just wanted to know the best approach. There are many problems in LC and is almost impossible for me to go through each and every question. Is there a way like solving problems based on a company or the topics like Arrays etc or that on the feed in the website.
Also I would like to know if there is a group here (practice group or something) that can work together and target some problems for the day or week to keep me accountable.

Please suggest.

Thanks.
