Sure, here is a Python solution using Kadane's algorithm. This algorithm is used for finding the largest sum of a contiguous subarray in an array of integers.

```python
def max_subarray_sum(arr):
max_current = max_global = arr[0]
for i in range(1, len(arr)):
max_current = max(arr[i], max_current + arr[i])
if max_current max_global:
max_global = max_current
return max_global

arr = [9, -2, -1, -3, 4, -1, 2, 1, -5, 4]
print(max_subarray_sum(arr)) # Output: 6
```

Here's how it works:

1. Initialize `max_current` and `max_global` with the first element of the array.
2. Loop through the array starting from the second element.
3. For each element, calculate `max_current` as the maximum of the current element and the sum of the current element and `max_current`.
4. If `max_current` is greater than `max_global`, update `max_global` with the value of `max_current`.
5. After the loop ends, `max_global` will hold the largest sum of a contiguous subarray.
