Hi,

My tests are failing for some reason, I see that my program prints "$ " but still assertion fails. Here’s the logs from my test run, hoping it might help:

```auto
Initiating test run...

⚡ This is a turbo test run. https://codecrafters.io/turbo

Running tests. Logs should appear shortly...

[compile] Moved ./.codecrafters/run.sh → ./your_program.sh
[compile] Compilation successful.

The Issue was in my code I was doing fmt.Println() which was introducing new line character. but the cmd that I was executing already had new line character. Switching to fmt.Print() worked out.
