Plz Can someone give some explanation i didn't get what is the problem??

Well, I was scrolling to the editor when I completed reading the task, but all of the code was already written.... I submitted and it passed all test cases. Don't understand where is the trick, but I suggest moderators to review what is just happened :)

I really don't get the sample, 5 2 0 1 3 3 2 0 0 3 2 3 where it says by removing either stain of index 1, 4 2, 1 ( 1 - based ) would require the minimum area of single rectangular clothe. However, If ( 1, 4 ) is removed, ( 3, 3 ), ( 2, 0 ), ( 2, 3 ) will remain on the grids, which costs 2 * 4 = 8 area. And if( 2, 1 ) = ( 1, 2 ) is removed, ( 2, 0 ), ( 0, 3 ) , ( 2, 3 ) will remain, which costs 3 * 4 = 12, where it shouldn't be. Am I missing something? Thanks in advance.

Personally, I think this should be in the "combinatorics" section, since there is a combinatorial method using O(1) space and O(N) time.

That said, I've been using the problems on this site to learn DP, and I cannot for the life of me understand the DP solution in the editorial. Without any more spoilers than I might have already incidentally revealed, does anyone have any further insight on the editorial solution? ... Perhaps a textbook which elaborates on the particular tool from the editorial?
