Given the table image, tell me the locations of the subsequent table cells. Represent the cell location with JSON {'value': '<cell value>', 'location': (Row_ID, Column_ID)} where both Row IDs and Column IDs begin from 1.
(1) '46.46'
(2) '49.60'
(3) '506'
(4) 'heat'
(5) 'final'
(6) 'hector cotto'
(7) '110 m hurdles'
(8) '514'
(9) '10'
(10) 'felix martinez'
(11) '546'
(12) '13.73'
Some cell values may not be contained in this table. If so, represent their locations as 'DOES NOT EXIST'.

The target cell locations are as follows:
(1) {'value': '46.46', 'location': (6, 3)}
(2) {'value': '49.60', 'location': (4, 3)}
(3) {'value': '506', 'location': 'DOES NOT EXIST'}
(4) {'value': 'heat', 'location': (1, 3)}
(5) {'value': 'final', 'location': (1, 9)}
(6) {'value': 'hector cotto', 'location': (3, 1)}
(7) {'value': '110 m hurdles', 'location': (3, 2)}
(8) {'value': '514', 'location': 'DOES NOT EXIST'}
(9) {'value': '10', 'location': (5, 4)}
(10) {'value': 'felix martinez', 'location': (6, 1)}
(11) {'value': '546', 'location': 'DOES NOT EXIST'}
(12) {'value': '13.73', 'location': (3, 5)}
