[@philipmenke7741]

Much clearer explanation then the solutions leetcode has written up, thank you!

[@olegkovtun5011]

Thanks man, it is very instructive!

[@tvsnath]

Much clear explanation. thank you.

8:05 why do you take max? We want to buy the lowest price right

[@saianishmalla2646]

Yeah so you need to understand that the value is actually referring to the profit like you said we want the lowest price. When you buy your profit decreases which is why we choose the value where we lose less of our profit.

[@ParthPatel-ji1up]

@@saianishmalla2646 @nands , i think a better word instead of profit there is balance. when we buy, our balance becomes less. which we want to buy with whatever that makes the balance the highest (decrease by the least).

Hahahaha thanks Vaibhav 😂😂

[@mikasaackerman2694]

Great Explanation! Would you also make a video of Buy and Sell Stock where the transactions are generalized to k?

[@Greatasfather]

Hey what do you do for variable number of transactions

[@jeneyify]

I have been following you as I have started leet coding. Amazing explanation, but how do we reach that level where we're able to think of such solution without any help

[@parthpatel8532]

You can reach that level by 2 ways. 1. Keep trying and trying until you get an answer. This is the bad way. You'll waste alot of time. 2. When you cant solve a problem in 2 days, come to youtube or something and search for the solution. Learn how the solution is created including patterns used. And in the future when a similar problem arises, you'll know how to solve it. The goal isnt to solve all by yourself. The goal is to learn the patterns and where to use each one!

The part that I find a little hard to wrap my head around is we're doing two transactions in a single iteration, unless I work it out, I probably don't think that part is all that intuitive, not saying the solution is the problem, my understanding is the problem :)
