[Pattern] Change in wording

Dear PuzzleUp Contestants,

A number of fellow PuzzleUp contestants have sent remarks and asked for the clarification of the term "rotate" used in the question. After reexamining the text, we decided to use a clearer wording as follows: "...rotating another pattern (90, 180 or 270 degrees)".

We would like to thank all fellow PuzzleUp contestants who contributed to the clarification with their remarks. Our apologies for any inconvenience.

Have a nice competition.

PuzzleUp Team
