A table may have multiple cells. We can utilize the json format {'value': '<cell value>', 'location': (row number, column number)} to store a cell's positions in a table, where both row and column number start from 1. I am providing you a table image. Please tell me the positions of the cells mentioned below using the above format. Some cell values may not be contained in this table. If so, represent their locations as 'DOES NOT EXIST'.
Values to locate:
1. 'Cardiac arrest'
2. 'Not smoking, physical activity, maintaining a healthy weight'
3. 'Prevention'
4. 'Description'
5. 'Survival rate ~ 10% (outside of hospital) 25% (in hospital)'
6. 'Symptoms'
7. 'Specialty'
