Sure, here are some exceptions that could occur when dealing with file I/O in the context of DSA:

File not found: This exception occurs when the file that you are trying to open does not exist.
Permission denied: This exception occurs when you do not have permission to access the file that you are trying to open.
Read error: This exception occurs when there is an error reading from the file.
Write error: This exception occurs when there is an error writing to the file.
EOF: This exception occurs when you reach the end of the file.
Corrupted file: This exception occurs when the file is corrupted and cannot be read or written to.

To avoid these exceptions, you can use the following tips:

Make sure that the file exists and that you have permission to access it.
Use a try-catch block to handle errors that occur when reading from or writing to the file.
Use a buffered reader or writer to improve performance and reduce the chances of errors.
Use a checksum to verify the integrity of the file before you open it.

By following these tips, you can help to avoid exceptions when dealing with file I/O in the context of DSA.

Here are some additional tips for handling file I/O exceptions:

Use a debugger to step through the code and see where the errors are occurring.
Use a unit testing framework to test your code for exceptions. This can help you to find and fix errors before they cause problems in your production code.
Use a logging framework to log errors. This can help you to track down errors and troubleshoot problems.

By following these tips, you can help to manage exceptions when working with file I/O and ensure that your code is correct.
