Final 3sum question is a little tricky. The only way it could have been optimised is by using two pointer approach after sorting the array. Even after that complexity would have been O(n^2)

[@felixb8418]

I think the video highlights 2 key learning points: 1) Don't put everyone on a pedestal purely because of their background, education and upbringing. These Harvard students suck at programming. If you start with the impression that you are inferior to them, then you are sabotaging yourself. 2) The power of daily self-improvement. Doing Leetcode everyday might be hard at first, but you quickly get much better than people who are paying $50 000/year. It's not where you come from, it's where you are going and what steps you are taking to get there!

[@darkferiousity]

Got one for you guys: Shifted square problem...4 squares stacked...2 colums 2 rows...shown from the side open cv gives out unorganized (x,y) coordinates/points in a multidimensional array. There are 16 points in the array. I need to organize them so that each point matches it's corresponding square side and give an id to each square starting at 1 from top left to right then bottem left to right. Important that the bottem left square is shifted slightly further left than the left top square and the top right square is shifted up more so than the top left square. Edit: The squares might be rotated and one last thing is the center of each square needs to be determined. Each squares dimensions are 2 units high by 4 units long.

[@ZantierTasa]

What on EARTH are you talking about? This is so badly explained and underspecified. -Why is it a "multidimensional array" of points? -What is it to "match"? -What is a "square side"? -How are the "id"s relevant? -What determines the positions of the "squares" (that are actually recrangles, from the dimensions you gave), and whether they are rotated or not?

[@darkferiousity]

@@ZantierTasa @Zantier Ta'sa @Zantier Ta'sa Zantier if you were paying attention. I gave you out all the information you would need. Multidimensional as in points = [(x,y),(x,y),...], there are 16 points/coordinates. Sorry my bad shifted rectangles*....This problem could be applied to squares as well does not really matter. A match would be: match = [(x,y),(x,y),(x,y),(x,y)] determining a match is up to you. The ids were just for organizing the matches of points. You could also just organize the matches using a different way if you prefer as long as the 4 points for each square/rectangle are seperated from the other. I gotta go to work, but I could draw you out an example. I can clarify more, but not gonna write out a lot on a youtube comment.

[@ZantierTasa]

@@darkferiousity That isn't multidimensional, that's a 1-dimensional array of coordinates. You still haven't said what "square side" is, or what it means to "match". Like if there's 16 points, can I just return the whole list of 16 points, and call that a match?? What am I matching? You've just said there's points and rectangles, and I have no idea if I'm given coordinates for the rectangles, or if I'm supposed to figure out where the rectangles go. A diagram would help, sure. Or an explanation would help, too.

[@darkferiousity]

@@ZantierTasa 1 dimensional array = [x, y, x, y, x, y.....] multidimensional = [(x,y), (x,y)....] a match would be 4 points per square/rectangle

[@darkferiousity]

@@ZantierTasa no coordinates are given because this should match for any coordinates
