So let me create this puzzle to freshen you up!
It is inspired by a meta question: Yet another 2018 puzzle.
Put the digits 2, 0, 1, and 8; exactly once for each grid color -- excluding black -- (some of them are already put and denoted by a black font-color) so that there is at least one row/column which has the numbers whose sum is 0, 1, 2, 3, and so on until 11.
There are also additional numbers denoted by red font-color which will be included on the sum of its row and column. The row or column that doesn't have any number will be having null (not zero) sum.
Clarifications: There are 5 rows and 10 (err.. 11) columns here, where the first row currently has the sum of 7 (-1 plus 8) and first column has null.
