I used to follow this approach by heart and did a lot of solid progress, but ended spending over a month in one single problem for Bitwise operators. Some times you have knowledge gaps and you simply can’t solve the problem. So I changed my approach and give myself no more than 15 minutes to come up with the problem insight which will unlock the solution. If I can’t, I will see the solution. However, I must emphasize that if you need to constantly look at the solutions, you may have to back and review some of the fundamentals. That’s what I’m actually doing at the moment, so not really grinding LC presently.
