How to use leetcode? (Disclaimer : this is the approach I took, and it helped me. The timeframe could vary depending on the individual skills)
Stage - 1 (Easy and Medium : 85+ and 165+ problems) Select your favorite topic, solve easy ones, OR sort by acceptance rate. After easy ones are solved, move to other topic if you’re exhausted, OR solve medium ones. Don’t even attempt for the hard ones if you’re not comfortable with easy or medium.
