6	9

7	2, 4, 5

8	1, 1, 3, 5, 6, 7, 7, 8

9	0

In this task, you are provided with a table image and several target cells. You are required to determine the positions of these cells, which can be represented in the json {'value': '<cell value>', 'location': (row_id, column_id)}, with both row id and column id start from 1. Some cell values may not be contained in this table. If so, represent their locations as 'DOES NOT EXIST'.
Cell values are shown below:
CELL VALUE 1: '1, 1, 3, 5, 6, 7, 7, 8',
CELL VALUE 2: '7',
CELL VALUE 3: 'Stem',
CELL VALUE 4: '8',
CELL VALUE 5: 'Leaf ',

The target cell locations are as follows:
CELL LOCATION 1: {'value': '1, 1, 3, 5, 6, 7, 7, 8', 'location': (5, 2)}
CELL LOCATION 2: {'value': '7', 'location': (4, 1)}
CELL LOCATION 3: {'value': 'Stem', 'location': (2, 1)}
CELL LOCATION 4: {'value': '8', 'location': (5, 1)}
CELL LOCATION 5: {'value': 'Leaf ', 'location': (2, 2)}
