Given a square 2D list holding only 0's and 1's, determine the greatest number of 1's that can be covered by a square of smaller size. More formally, given an n x n 2D list in [row][col] order holding only 0's and 1's, and an integer k <= n, determine the greatest number of 1's that can be covered by a square of size k x k. Return a tuple with the number of 1's this optimal k x k square covers as the first element, the row of the top left corner of this optimal k x k square as the second element, and the col of the top left corner as the third element.

If several different k x k squares cover the same (maximum) number of 1's, return the row, col pair of the top left corner of the top left optimal placement, i. e., the placement for which row + col is smallest. There will not be a case where multiple optimal placements with the same row + col sum exist. If given k=0 or an empty 2D list, return 0 for the number of 1's covered, 0 for the row and 0 for the col.

i want to say d but i could be wrong however it is organized if that could happen..

hope it could

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
