There are 5 shapes on a 4x4 grid. Which shape is closest to the cyan rectangle in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: cyan rectangle at (3, 3)
Distance from target shape to orange trapezoid at (0, 0): 6
Distance from target shape to blue rectangle at (2, 1): 3
Distance from target shape to yellow right_triangle at (2, 2): 2
Distance from target shape to brown right_triangle at (0, 1): 5
Closest shape is the yellow right_triangle at (2, 2) with distance 2</think>
