Taking all of this into consideration, a Set is the best data structure for performing fast checks for row/column inclusion and works with parameter arrays that may be unsorted or contain duplicates. now we are given a matrix full of positive integers.and an array of queries are also given, the format of the query is: [x, y, m], it represent we need to sort a submatrix with dimension of m*m, the left-top corner is [x,y].so we keep doing that until al I'm sure there are other ways, but in the meantime, how about this: Then again, the concatenation of matrixes might not be particularly if the key is found in any of the arrays, those rows or columns which the keys signify shoudl be discarded and not enter for loop for them.
