Walkthrough

A new Go solution file is added to challenge-1/submissions/Huansock/ containing a main function that reads two comma-separated integers from standard input, calls a public Sum function to compute their sum, and prints the result with error handling.

Changes

Cohort / File(s)	Summary
New Challenge 1 Solution challenge-1/submissions/Huansock/solution-template.go	New file with main function that reads two comma-separated integers from stdin, handles read errors, invokes Sum() to compute the total, and prints the result. Includes public Sum(a int, b int) int function returning a + b.

21-24: Remove the stale TODO comment.

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

Send parse errors to stderr to avoid contaminating judge output.

Error messages written to stdout can cause the challenge judge to treat the output as incorrect. Use fmt.Fprintln(os.Stderr, ...) instead.

🔧 Suggested change

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

Also remove the stale TODO comment on line 23—the function is already implemented.
