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:
Green Black Black Black Black Black Black Yellow
Green Black Green Black Green Green Yellow Black
Yellow Green Green Green Yellow Black Yellow Black
Black Black Black Black Black Black Black Black
Green Green Black Black Green Green Green Green
Yellow Black Yellow Black Black Black Yellow Green
Green Black Yellow Black Green Green Black Green
Black Green Green Green Black Black Black Yellow
Green Black Black Green Green Black Green Black
Yellow Black Green Black Yellow Black Green Black
Green Black Green Black Black Black Green Green
Black Black Black Black Black Black Green Green

Output:
Green


Example 2
Input:
