Clear the Binary Grid by Normalizing Row Patterns
A control room monitors a rectangular wall of indicator lamps arranged as an `m x n` grid named `grid`. Each lamp holds one of two binary states: `0` means dark and `1` means lit. Two kinds of master switches are wired to the wall. Using a row switch reverses the state of every lamp in one chosen row, and using a column switch reverses the state of every lamp in one chosen column. Each switch may be used any number of times, in any order. Return `true` if some sequence of switch uses leaves every lamp dark, and `false` if no sequence can.
