It is intended to read two positive integer values, x and then y, with x > y, and print the result of x-y. However, it currently doesn't work. It is missing a single command somewhere. Figure out what single command could be inserted somewhere in the program to make it work correctly. Which command is missing? Write exactly one of the eight Bf commands: If we call the position directly before the first "," Position 0, the position directly before the first ">" Position 1, the position directly before the second "," Position 2, etc.; at what position would you insert the missing command? Write a single digit integer:

# Bf Program Debugging Exercise

### Program Code:
```
,>,-[--<->]. 
```

### Objective:
This Bf program is designed to read two positive integer values, `x` and `y`, where `x > y`. It should print the result of `x - y`. However, the program is currently not functioning correctly because it is missing a single command. Your task is to determine the missing command and the correct position to insert it for proper functionality.

### Task:
Identify the missing command from the eight possible Bf commands (`+`, `-`, `<`, `>`, `[`, `]`, `.`, `,`) to make the program operate correctly.

### Positioning:
- **Position 0**: Before the first `,`
- **Position 1**: Before the first `>`
- **Position 2**: Before the second `,`
- Continue this pattern...

### Instructions:
1. Determine which Bf command is missing and write it in the provided space.
2. Identify the correct position to insert the missing command and write it as a single digit.

### Input Fields:
- **Missing Command**: [ ]
- **Position**: [ ]
