Given input-output grid pairs as reference examples, carefully observe the patterns to predict the output grid for new test input. Each pair follows the same transformation rule. Grids are 2D arrays represented as strings, with cells (colors) separated by spaces and rows by newlines.
Here are the input and output grids for the reference examples:
Example 1
Input:
Gray Purple Purple Purple Purple Gray
Gray Purple Purple Purple Purple Gray
Gray Purple Purple Purple Purple Gray

Output:
Purple Gray Gray Gray Gray Purple
Purple Gray Gray Gray Gray Purple
Purple Gray Gray Gray Gray Purple
Gray Gray Purple Purple Gray Gray
Gray Purple Gray Gray Purple Gray


Example 2
Input:
