if you are watching this in lockdown you are one of the rare species on the earth . many students are wasting their time on facebook, youtube, twitter, netflix, watching movies playing pubg, but you are working hard to achieve something . ALL the best ...nitj student here
Nice initiative dude. I'd advice you to give a proof of concept of the algorithm you are walking through, like why this would actually always work. For some algorithms its trivial but for some it's not. Its always good for the sake of completeness. Like in this example, for every column_start and column_end combination you are finding the maximum submatrix and then taking the max of all those combinations. Anyways, a really good initiative and keep up the good work.
When understand same the algorithm from other source, then time complexity of understanding the algorithm is O(n^2). But listening your lecture on same algorith, then time complexity of understanding is reduce to O(n). 🙂🙂🙂
thanks for the video Tushar...! if the size of sub-matrix is already given then what can be the best approach to solve this problem. ( i think naive approach will cost n^4 ).
I found this link on geeksforgeeks, u explained this algorithm much better than geeks , it really helped me to understand what actually is going on. Will u plz make more videos of some difficult article which r on geeksforgeeks
