 So the other day I was doing this problem called equal rectangles and basically this problem just boils down to you have like a bunch of sides and you need to make sure that you need to check if you can actually make four rectangles that have the same equal area, right? So that's what this problem was about. And what I learned from this problem is that a lot of these problems, they actually try to make you overthink the problem and then you end up trying to do something like completely different and then you realize the solution is actually super super easy. So what I learned from doing these problems that so in this in this problem like ordinarily if you just read this problem and you were like okay make equal areas right so I need to make four rectangles equal areas so I'm just gonna go through every single four but brute force every single four subsets until I get to an equal area and that's pretty difficult to do. I'm not gonna lie that's actually pretty difficult to do so I had trouble just writing the brute force solution out because that takes time and a lot of effort. So yeah it took me like a few submissions and I realized like this problem and I decided you know what screw this I'm just gonna look at the editorial and looking at the editorial all you had to do is just sort it right you just had to sort the numbers so you didn't actually have to like brute force anything all you had to do is sort it and then compare the first and last problem of multiply first and last values until you get to the center and then you could you just check if you had four rectangles with the same area. So what I realized a lot about competitive programming is that just don't overthink problems you know a lot of these problems a lot of problems in division 3 or division 2a and 2b are actually pretty easy it's just a trick that you have to figure out if you could find the trick you easily could solve the problem there's a reason why a lot of the top math people generally do well in these problems is because they they define the trick very easily and then they're able to solve it so yeah don't don't overthink these problems sometimes are very easy to figure out sometimes you don't even have to like go through every single possible combination sometimes it's super easy maybe you just have to sort it maybe you have to find I don't know maybe you have to use two for loops maybe two pointers something around those lines and then if you could figure out the problem or maybe you have to use a math equation it's that that's it that's all there is to it but yeah that's all I have to say for this video very calm subscribe I could not actually make a tutorial today I'm so sorry but yeah I'll check you guys later
