<s>[INST] In this problem, you are asked to read a stream of integers until you reach the end of the stream (EOF), and print the sum of the entered integers with some formatting applied.

Here's the sample code for your reference.

```python
# 1. Basic Sample (Incorrect)
x = 1
sum_x = 0
while x != '':
    x = input()
    sum_x += int(x)
print(sum_x)
```

However, I'm getting an "EOFError" when running this code. There are several ways to fix this, but could you explain to me the reason behind this error, and provide some alternative implementation strategies to overcome this issue?[/INST]
