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:
Yellow
Purple
Orange
Pink

Output:
Yellow Yellow
Purple Purple
Orange Orange
Pink Pink


Example 2
Input:
Pink
Orange
Yellow
Blue
Red

Output:
Pink Pink
Orange Orange
Yellow Yellow
Blue Blue
Red Red


Example 3
Input:
Orange
Gray
Brown
Yellow
Yellow

Output:
Orange Orange
Gray Gray
Brown Brown
Yellow Yellow
Yellow Yellow


Here is the input grid for the test example:
Input:
Gray
Pink
Gray


Directly provide the output grids corresponding to the given test input grids, based on the patterns observed in the reference examples.
