Changes

Cohort / File(s)	Summary
New solution submission challenge-1/submissions/redstrike/solution-template.go	Adds main function with Scanf-based input reading, error handling, and output. Implements exported Sum(a int, b int) int function returning the arithmetic sum of two integers.

10-14: Consider improving error handling to follow Go best practices.

Error messages should be written to stderr, and the program should exit with a non-zero status code on failure.

Apply this diff to improve error handling:

+import (
+	"fmt"
+	"os"
+)
+
 func main() {
 	var a, b int
 	// Read two integers from standard input
 	_, err := fmt.Scanf("%d, %d", &a, &b)
 	if err != nil {
-		fmt.Println("Error reading input:", err)
-		return
+		fmt.Fprintln(os.Stderr, "Error reading input:", err)
+		os.Exit(1)
 	}

1-5: LGTM!

Clean package declaration and minimal imports appropriate for the functionality.

---

10-10: Verify the input format matches challenge requirements.

The format string "%d, %d" expects integers separated by a comma and space (e.g., "5, 3"). Ensure this matches the exact input format specified in Challenge 1.

---

21-24: LGTM!

The Sum function correctly computes the sum of two integers. Note that the exported name (capitalized) is unusual for package main since it's not typically imported, but this may be required by the challenge test framework.
