This one turned out pretty long, but I hope the timestamps are helpful Also, the code for all 3 solutions is in the description 😃 Comment from : NeetCode

terrible explaination, this video is trash Comment from : amerigo_wespuczi

"And this path, will never have any(one)" 4:05😢 Comment from : Varcel

This explanation was very difficult for me to understand, as it sounded a bit disorganized Appreciate the upload regardless Comment from : Blezerker

I fail to understand the table that is introduced at 8:05 Comment from : Sekiranda Hamza

Thanks for the video! I had to draw out the recursion tree of your solution to really understand it Definitely a more challenging problem Comment from : Edwin Francois

Why does his drawing show an array with three rows but when you run the code it's setup like this?brbr[[1, 1, 1, 1], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]] Comment from : Brandon Davison

I have Amazon interviews this week I hope I will crack it Comment from : Samrat Dutta

this was a terrible explanation lol: extremely scattershot, seemingly confusing yourself as you were explaining each step, addressing future problems halfway through the explanation for current problems, etc brbrIt almost feels like you solved the problem 5 minutes before, and realized you had 10 minutes to make the video, but instead of putting it off for another day, you just rushed through itbrbrIncredibly unlike your usual explanations, which are often concise, structured, and well thought out Comment from : Yek Xi

The code and the graph you draw is reversed direction, was hard to figure out already Comment from : ZT Luo

this question is medium?? wowwwwwww Comment from : ROB R

In the decision tree for the memoization solution, we're making at most 3 decisions but in the code you're only making 2 decisions What am I missing here? Comment from : Jason Thai

Thanks, it really helps me a lot! Comment from : Oscar Chan

@NeetCode Can you please split this video and explain each of the solutions separately with a walkthrough of the code It was difficult to follow this way Comment from : Dolly Vishwakarma

this should be named coin change 4 lol Comment from : Zain

It will be better if you can explain the recursion solution code with the illustration together Comment from : Wilson Wang

excellent! Comment from : Ho Yin Li

I'm living on your channel❥ Comment from : Annies Box

i have it crazy that interviewers expect you to have never seen this problem and answer it in an hour Comment from : Zahaan Khan

At 3:50, in the explanation that was given to prevent duplicates, what would happen if we continue going down the left-most 1 path? If the choices of {1,2,5} are still on the table, how is that logic going to prevent duplicates that start with a 1? For example, [1,1,1,2], [1,1,2,1], and [1,2,1,1] Wouldn't those 3 sequences show up as distinct paths on that left-most sub-tree of 1? Perhaps I am misunderstanding it, any explanation would be helpful! Great video overall! Comment from : Cong R

From coin change to coin change 2 it's a big jump pretty big to be honest shit man Comment from : Pritam

Thanks for the video! Could you also cover 'Minimum Cost For Tickets' which is one of DP problems chosen from you? Comment from : J

great video btw Comment from : director
