## Recursion Trace for Function Execution: ReverseArray(A, 0, 4)

Given Array A = {4, 3, 6, 2, 5}

### ReverseArray(A, i, j)
#### Description:
- **Input**: Array A and nonnegative integer indices i and j
- **Output**: The reversal of the elements in A starting at index i and ending at j

#### Pseudocode:
``` 
if i < j then
    Swap A[i] and A[j]
    ReverseArray(A, i + 1, j - 1)
return
```

#### Detailed Explanation:
1. **Initial Call**: ReverseArray(A, 0, 4)
   - **Condition Check**: 0 < 4 (True)
   - **Swap**: A[0] and A[4] ➔ {5, 3, 6, 2, 4}
   - **Recursive Call**: ReverseArray(A, 1, 3)

2. **First Recursive Call**: ReverseArray(A, 1, 3)
   - **Condition Check**: 1 < 3 (True)
   - **Swap**: A[1] and A[3] ➔ {5, 2, 6, 3, 4}
   - **Recursive Call**: ReverseArray(A, 2, 2)

3. **Second Recursive Call**: ReverseArray(A, 2, 2)
   - **Condition Check**: 2 < 2 (False)
   - **Return**: No swap or further recursive call

**Final Reversed Array**: {5, 2, 6, 3, 4}
