Can you place every number from 1 to 9 into a 3x3 grid such that the median of every row and column is a unique value? The median of a row is the number that is greater than one number and smaller than another number in that row (similarly for columns).
Bonus question: Can you find 4 different solutions, such that 2, 3, 4, or 5 are not used as medians?
Good luck!
