    ### Instructions:
    
    1. Thoroughly understand the rule provided. If needed, break down the rule into simpler components or steps.
    2. Apply the rule carefully to address the question presented.
    3. Verify your answer to ensure it aligns with the rule and the context of the puzzle.
    
### Calcudoko Puzzle Rule:

1.Calcudoko is a sudoku-like game. The game is played on an NxN grid. In each row and column, fill in the numbers from 1 to N. 
2.As in sudoku, each number can appear only once in each row and column. 
3.The grid is divided into groups, each of which has a target number and an operator that indicates that the numbers in the group must equal the target number after a specified operation.
4.The operations :
    4.Sum: + The numbers in this group must add to the target value.
    4.Difference: - One of the numbers in this group, minus the rest, must equal the target value (the number to be subtracted from may be any of the cells).
    4.Product: * The numbers in this group must multiply to produce the target value.
    4.Ratio: / One of the numbers in this group, divided by all of the others, must equal the target value. As in a difference group, which of the cells contains the number to be divided is not specified.
5.Numbers may be repeated within a group (so long as they're not also repeated within a row or column).  
6.Puzzles are parsed in a "puzzle spec" format, where rows are given one per line, with cells separated by spaces. Groups are labelled with alphabetic characters, which are then used to identify cell membership. 

### Question

Now the "puzzle spec" of a Calcudoko is: 
{self.grid} 

The answer needs to provide the corresponding numbers for all positions in the Calcudoko.

Calcudoko is a sudoku-like game. The game is played on an NxN grid. In each row and column, fill in the numbers from 1 to N. 
As in sudoku, each number can appear only once in each row and column. 
The grid is divided into groups, each of which has a target number and an operator that indicates that the numbers in the group must equal the target number after a specified operation.
Sum: +
The numbers in this group must add to the target value.
Difference: -
One of the numbers in this group, minus the rest, must equal the target value (the number to be subtracted from may be any of the cells).
Product: *
The numbers in this group must multiply to produce the target value.
Ratio: /
One of the numbers in this group, divided by all of the others, must equal the target value. As in a difference group, which of the cells contains the number to be divided is not specified.

Numbers may be repeated within a group (so long as they're not also repeated within a row or column).
