Can You Place Every Number from 1 to 9 into a 3×3 Grid?

Here is expert analysis about Can You Place Every Number from 1 to 9 into a 3×3 Grid.

For finding in the whole matrix, the complexity is N*log M with binary search. Then first find the minimum and maximum element from the N*M matrix. Apply Binary Search on that range and run the above function for each x. If the number of elements in matrix ≤ x is 1 + N*M/2 and x contains in that matrix then x is the median.
