11-14: Consider exiting with non-zero status on error.

When input reading fails, the program returns without signaling an error via exit code. In Go best practices, error conditions should typically exit with a non-zero status to indicate failure to the calling process.

🔎 Suggested improvement

+import (
+	"fmt"
+	"os"
+)

 	_, err := fmt.Scanf("%d, %d", &a, &b)
 	if err != nil {
 		fmt.Println("Error reading input:", err)
-		return
+		os.Exit(1)
 	}

⚠️ Potential issue | 🟡 Minor

Remove stale TODO comment.

The TODO comment on line 23 states "TODO: Implement the function," but the function is already implemented on line 24. This comment is misleading and should be removed.

🔎 Proposed fix

 // Sum returns the sum of a and b.
 func Sum(a int, b int) int {
-	// TODO: Implement the function
 	return a + b
 }

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	// Sum returns the sum of a and b.
	func Sum(a int, b int) int {
	// TODO: Implement the function
	return a + b
	}
	// Sum returns the sum of a and b.
	func Sum(a int, b int) int {
	return a + b
	}

In challenge-1/submissions/amanabay/solution-template.go around lines 21 to 25,
remove the stale TODO comment on line 23 that says "TODO: Implement the
function" because the Sum function is already implemented; simply delete that
misleading comment so the code and comments are consistent.
