Summandum

Deduce the hidden row and column headers from the sums inside the grid.

Controls

Each row and column has a hidden header. The headers use every number from 0 to N−1 exactly once. A number in a cell is the sum of its row header and column header. Select a row or column header, then choose a number. Fill all headers so every shown sum matches.
