Can someone help me solve this?

**Merge Sort Challenge Activity: Level 1**

### Task Description
In this activity, you are given the following list of numbers:
```
numbers: 38, 39, 72, 12, 31, 51
```

You are required to perform a merge operation on the subarray defined by the range `(0, 2, 5)`. Specifically, you will fill out a table that keeps track of the positions (leftPos and rightPos) and the elements as they are copied into `mergedNumbers`.

### Provided Instructions
**Merge(numbers, 0, 2, 5) is called. Complete the table below for leftPos and rightPos at the moment an element is copied into mergedNumbers.**

### Table to Complete
```plaintext
| mergePos | leftPos | rightPos | Element copied to mergedNumbers |
|---------------------------------|-----------------------------|
| 0       |       0     |        3        |              12                                   |
| 1       |       2     |        4        |              31                                    |
| 2       |       2     |                 |              38                                  |
| 3       |       1     |                 |              39                                    |
| 4       |                 |        5        |              51                                    |
| 5       |                 |                    |              72                                    |

 *Example: for mergePosition 0, leftPos is 0, rightPos is 3 and the element copied is 12.*
 ```

### Directions for Completion:
1. Start from the specified subarray.
2. Compare the elements from the left and right parts of the subarray.
3. Copy the smaller element to `mergedNumbers`.
4. Update `leftPos` and `rightPos` accordingly.
5. Continue until all elements in the subarray are processed.

### Explanation of the Table Columns:
- **mergePos**: Position in the merged array where the current element is to be copied.
- **leftPos**: Position in the left subarray from where the current element is taken.
- **rightPos**: Position in the right subarray from where the current element is taken.
- **Element copied to mergedNumbers**: The specific element that is copied into the merged array at the current merge position.

### Visualization
Below the table, a visual progress bar is presented, indicating the progress through at least the first four
