You have been given a blank 31 x 31 grid as shown below. Each square in the grid is either "light" or "dark".
The numbers to the right of the grid represent the consecutive sequences of "light" squares in each row while the numbers in the bottom represent the consecutive sequence of "light" squares in each vertical column.
For those interested in text (edited to fix line breaks).
