Walkthrough

Adds a new Go program file for Challenge 1 that implements an exported Sum function accepting two integers, reads comma-separated integers from standard input, calls Sum with the parsed values, and prints the computed sum.

Changes

Cohort / File(s)	Summary
Challenge 1 Solution challenge-1/submissions/manish-npx/solution-template.go	Adds new file with exported Sum(a int, b int) int function and main program that reads two comma-separated integers from stdin, invokes Sum, and prints the result; includes input error handling

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~3 minutes

• Single new file with straightforward logic (input parsing, integer addition, output)
• Verify input error handling is correct and matches expected format
• Confirm Sum function is properly exported with correct signature

11-14: Consider Go best practices for error handling.

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

Apply this diff to follow Go error handling conventions:

+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)
 	}

⚠️ Potential issue | 🟡 Minor

Remove the stale TODO comment.

The function is already implemented, so the TODO comment is misleading.

Apply this diff:

 // 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

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

In challenge-1/submissions/manish-npx/solution-template.go around line 23,
remove the stale "// TODO: Implement the function" comment because the function
is already implemented; delete that single-line TODO to avoid misleading future
readers and leave the implemented code intact.
