Pull Request Overview

This PR enhances error handling in the code editor by displaying compilation and runtime errors from the Judge0 API in the output section instead of only showing a generic snackbar notification.

• Added a utility function to decode and format error messages from the Judge0 API
• Enhanced error handling to display stderr and compile_output errors in the output section
• Refactored stdout processing to use the new decoding utility function

The function name decodeFormat is ambiguous. Consider renaming it to decodeBase64Output or parseBase64Response to clearly indicate it decodes base64-encoded data and formats it as an array of lines.

Suggested change

	const decodeFormat = (data) => {
	const decodeBase64Output = (data) => {

[nitpick] Consider combining both error conditions to avoid duplication. You could use setOutput(decodeFormat(data.stderr || data.compile_output)) since both handle error scenarios similarly.

Suggested change

	setOutput(decodeFormat(data.stderr));
	} else if (data.compile_output) {
	setOutput(decodeFormat(data.compile_output));
	setOutput(decodeFormat(data.stderr || data.compile_output));
