Off and On (Posted on 2017-01-29)

When completed, the below tableau will have five 1's and five 0's in each row and in each column. Within any row or column, no three zeros or ones will be in successive positions--two in a row of either is a max (but there's no limit diagonally).

Complete the fill with 1's and 0's in accordance with the above rules.
