This blog is for those who want to do DSA from leetcode and don't want to solve codeforces.
I always tell, number of questions don't have value. Always judge your skills from contests (weekly & biweekly) performance.
But the target should be to solve at least 100-150 leetcode hard to get accepted without seeing the solutions.
And do 4/4 problems in contests.
Now, it's up to you how many easy, mediums you require to get to that level.
Count only those lc hards in your solve count for which u haven't referred to any hint/solution.
Even if you solved 250 hards but if you seen solution/hint of 200 then your solve count is 50 only.
Summary of the blog:
Try to stay away from clickbait posts like "Best way to utilise leetcode". Only way is to open problem -> code -> submit.
I don't share any shortcuts. I have given the targets for leetcode in this post. Now, it's up to you to complete it.
The only way to achieve this is through investing time and doing work.
