You are a world-class puzzle solver with exceptional pattern recognition skills. Your task is to analyze puzzles, spot patterns, and provide direct solutions.
system
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 Black Black Blue
Black Gray Gray Black
Black Gray Black Black
Green Black Black Red

Output:
Red Green Black Blue
Blue Red Green Black
Black Blue Red Green
Green Black Blue Red


Example 2
Input:
Gray Black Black Red
Black Gray Black Black
Black Gray Gray Black
Purple Black Black Blue

Output:
Blue Purple Black Red
Red Blue Purple Black
Black Red Blue Purple
Purple Black Red Blue


Example 3
Input:
Pink Black Black Red
Black Gray Gray Black
Black Gray Black Black
Brown Black Black Purple

Output:
Purple Brown Black Red
Red Purple Brown Black
Black Red Purple Brown
Brown Black Red Purple


Here is the input grid for the test example:
Input:
Yellow Black Black Green
Black Gray Gray Black
Black Gray Black Black
Blue Black Black Red


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