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:
Brown Brown Yellow Black Black
Black Yellow Brown Black Brown
Black Black Black Brown Black
Black Black Black Black Black

Output:
Brown Brown Brown Brown Black
Brown Brown Brown Brown Black
Brown Brown Brown Brown Black
Black Brown Brown Brown Black


Example 2
Input:
Yellow Blue Black Yellow
Black Black Black Black
Black Black Yellow Black
Black Black Black Black

Black Yellow Brown Yellow Black


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