Finalized

Hello, wanna finalize the advices on doing leetcode, I hope these are the crucial at any stage you are: 1. Try to solve it on your own (keep trying for atleast 45min - 1hr if you can't figure it out) 2. If you are not able to solve it, don't jump on to youtube, rather go in discussion section, and understand other code and write it by yourself. 3. if you have solved it, don't hop on to next sum, just go to Leetcode editorial for solution and look on to the other ways to solve and implement it, it is the destination where we learn the stls or collection whatever, it's the most important, I repeat. I figured out the 3rd step today, so just letting you know. Let me know the 4th if you heard less and something you feel that you figured it out, and might be helpful if you have known it before... over.
