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:
Black Blue Black
Blue Blue Blue
Black Blue Black

Output:
Blue Blue Blue Blue
Blue Black Blue Black
Blue Blue Blue Blue
Blue Black Blue Black


Example 2
Input:
Black Green Black
Green Green Green
Black Green Black

Output:
Green Green Green Green
Green Black Green Black
Green Green Green Green
Green Black Green Black


Example 3
Input:
Black Red Black
Red Red Red
Black Red Black

Output:
Red Red Red Red
Red Black Red Black
Red Red Red Red
Red Black Red Black


Here is the input grid for the test example:
Input:
Black Yellow Black
Yellow Yellow Yellow
Black Yellow Black


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