There are 3 shapes on a 10x10 grid. Which shape is closest to the yellow square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: yellow square at (0, 0)
Distance from target shape to red right_triangle at (2, 2): 4
Distance from target shape to cyan right_triangle at (9, 8): 17
Closest shape is the red right_triangle at (2, 2) with distance 4</think>
